If you want to use Mastodon through a command line interface (CLI) or text-based user interface (TUI), there’s a free open source tool you can install called “toot” ⧉.
It can be installed on a variety of Linux distributions and Mac too.
(By the way, despite the similar name, it has no connection to the mobile apps Toot! or Tooot.)
Posts in Mastodon can be set to automatically self-destruct after a certain time period, with exceptions made for posts you want to keep. Here’s how to do it:
If you want to stop deleting posts automatically, UN-tick the box marked Automatically delete old posts, and click the Save changes button.
No. Once a post is deleted it is gone. Be sure you want to use auto-deletion before you activate it.
If you delete a post that other people replied to, the replies to your post will be orphaned, and it will become impossible to discover or browse such discussions. If you want to keep certain discussions you’ve started in existence, make sure you include your posts from that discussion in the list of exceptions (see Step 4 in the instructions at the top of the page).
If you delete a post, any links to that post will immediately be broken and will just show an error message. If you want to keep a post, make sure it is covered by the exceptions list in Step 4 of the instructions.
If servers are busy, they create queues of tasks to work through. Automated deletion tends to go at the back of the queue, so it may take longer to happen than other tasks. If the settings are correct and it’s way past the deadline for the deletions to happen, ask your server’s admin for advice.
When this feature is discussed, the issue of server running costs is often raised:
You would have to speak to your server’s admin to find out exactly how it affects their setup, as different servers may have different resources available.
I asked a couple of very large server admins for their thoughts on how this balances out. Both of them said the added tasks were insignificant compared to everything else the servers have to do. Both of them also said deleting posts (especially posts with media attachments) saves storage, but one of them added that there may be fees to be paid if the deletions happen for very recent posts. On their server, it would be cheaper to only delete posts more than 90 days old, and leave any newer posts intact.
Fediverse groups are special kinds of accounts which let you connect with other people who share the same interest. You can join a group by following it.
At the moment, most Fediverse groups work like this:
It’s somewhat similar to following hashtags, and people who have used email discussion lists will also find this structure very familiar.
The main Fediverse group provider at the moment is Guppe ⧉. It’s platform-neutral, their groups can be followed from all kinds of Fediverse servers including Mastodon, GoToSocial, Friendica etc. It’s also free open source software so anyone can start their own Guppe server if they want to.
I’ve compiled a curated list of interesting Fediverse groups on fedi.directory ⧉. I’ve tried to only list active groups with a respectful atmosphere.
Guppe has a list of their top 50 active groups at the bottom of their website at a.gup.pe ⧉.
You can also try searching for @a.gup.pe in the search box on Mastodon, this will show Guppe groups that at least one person on your server is following. However, bear in mind if a group has no followers from your server it won’t show up in searches.
Guppe groups don’t require any kind of registration, you can create a group simply by mentioning the group name in the form “@YourGroupNameHere@a.gup.pe”. However, because there’s no registration there is no group moderator either. Guppe groups rely on members reporting bad group posts the same way they would report bad non-group posts.
Do exactly the same thing you would do if you saw spam/abuse outside the group on ordinary posts. Whatever kind of group you are following, you can report, mute and block just like you can with ordinary non-group posts.
When you report bad posts, the admins on your server (and possibly also the server of the spammer/troll) can take action to block it and remove it.
You can use Mastodon’s Lists feature to set up lists for groups, and then set those lists to hide posts from your Home timeline. This will let you keep groups in their own mini-timelines you can dip into whenever you want, without causing any posts to appear in your main timeline.
Hashtag follows and groups have some overlap, and appear to work in a similar way on the surface, but there are significant differences behind the scenes.
The biggest advantage of groups is you automatically see all of the group’s posts, even if they’re from accounts that haven’t federated to your server before. Because all the group’s posts are shared to all the members’ servers, you never miss a thing.
With hashtag follows, this mass federation doesn’t happen. Hashtag following means you will only see posts from accounts that already federate with your server. Hashtags are essentially passive filters for your server’s Federated timeline and do not actively draw in any new content.
Mastodon has been developing a built-in groups feature for some time now, but it hasn’t been released yet. From the screenshots posted so far, it seems it will be more of a Facebook Groups type forum rather than a public discussion list. (You can see highly technical details and screenshots of this upcoming Groups feature on their github page ⧉).
However, it is unclear if Mastodon groups will work across the Fediverse or only on Mastodon. Guppe is platform-neutral, and will work on any kind of Fediverse server that supports microblogging including Mastodon, Friendica and others.
Guppe is free open source software, and if you have the necessary technical knowledge and resources, you can install your own Guppe server by following the instructions on the Guppe Github site ⧉.
The Fediverse server type Friendica includes built-in group support, which works in a broadly similar way to Guppe. Creating a Friendica group requires a Friendica account, but anyone can join the group from other Fediverse server types including Mastodon servers.
A Friendica group can be moderated by the person who created it, and they can also add additional moderators to the same group.
On Mastodon, if you’re browsing someone’s profile page you can click the Media tab to just show their posts which have an attached image, audio or video file. Text-only posts and posts shared from other accounts are not shown in the Media tab.
The Media tab is especially useful if you’re browsing for works on an artist’s profile for example, or any account that posts interesting bits of media. It means you can go straight to specific works instead of having to scroll through non-media posts or boosted posts by other people.
Usually the tab is indicated by the word “Media”, but in some apps it may be an icon such a series of pictures.
Yes. There’s a media tab on your server’s website, the web app, the official apps and most of the third party apps. Most apps show this as a list of posts, but the web interface shows it as a grid of images where you click on an image to enlarge it.
If you’re browsing the Media tab on the web interface, you can see the original post the image comes from by clicking on the box icon just below the image in the bottom right corner.
No. The Media tab just shows media posts from that account. Shared media from other accounts are not shown in the tab.
No, it only shows posts with attached images, audio files or videos. Links that automatically generate a preview of media hosted elsewhere (such as YouTube links) are not counted as media posts.
If you’re posting an image on Mastodon and there is a particular part of the image that you want people to pay attention to, it is recommended that you set the image’s “focus” on this part. This setting tells Mastodon which part of the photo is most important, and it means Mastodon will prioritise showing that part of the image if it ever has to display a cropped preview version.
Here are some possible situations where people may see a cropped preview of your image on Mastodon:
Whatever the reason, people can still see the full non-cropped version if they click on the post or the image itself, it’s only the preview versions of images that may be cropped in certain circumstances.
(Some of these steps may be called different things or be done in a different order on different apps. Hopefully these instructions give you the general idea.)
Images aren’t cropped, but the preview versions of them may be cropped in certain circumstances. Even if people see a cropped preview, the original version is visible if people click on a post or the image itself.
On some versions of Mastodon’s web interface, and on some apps, timelines show all previews in a 16:9 aspect ratio. This means any images not in 16:9 are shown in cropped previews. People can click on the post or image to see the full original version, but while it’s on their timeline alongside other posts it may be shown cropped.
If you don’t adjust the focus, it will default to focusing on the exact centre of the image. This can cause portraits of people to be shown without their heads, for example.
The latest version of Mastodon’s web interface doesn’t crop previews of individual images any more, but people on other versions of Mastodon, other types of Fediverse server or other apps may see things differently. Also, attaching multiple images can cause cropping of previews on whatever you are using.
If you want a photo preview to look nice, it’s always worth adjusting its focus setting.
Images that have a 16:9 aspect ratio will not seem to show any differences when you adjust the focus setting, but it’s still worth adjusting the focus as some previews may be a different aspect ratio (for example if you’re attaching multiple images in a single post).
It depends on how many attachments you have, and what kind of software is being used by the person who sees your post. The aspect ratio of previews will usually change as you add more images and it tries to tile them together in your post.
Yes, you can use Mastodon’s edit feature to adjust the focus after the image has been posted.
Aspect ratio is how wide something is compared to how tall it is. For example, if an image is 1000 pixels wide by 1000 pixels tall, it would have an aspect ratio of 1:1. If it was 2000 pixels wide by 1000 pixels tall, it would have an aspect ratio of 2:1.
The 16:9 aspect ratio is very common on cinema screens, TV sets, laptops, smartphones, games consoles etc. The popular 1080p standard has pictures displayed at 1920 pixels wide and 1080 pixels tall, which means it has an aspect ratio of 16:9.
Individual images are no longer cropped to 16:9 on the latest version of Mastodon’s website, but not everyone is on the latest version, not everyone uses the website or the same apps, and not everyone is on Mastodon.
Also, if you’re attaching more than one image to the same post, then they will be shown as cropped previews whatever version you or other people are using.
Some third party Mastodon apps have a built-in draft posts feature.
There is no official drafts feature in the Mastodon website interface, but unofficially you can use the Delete & re-draft option combined with DMs to create drafts:
…but, as many people have pointed out, it might be easier to just use a notepad app and copy and paste drafts from a text file on your computer or phone 😁
On the Fediverse, and especially on Mastodon, if you follow an account by clicking the “Follow” button it changes into a “Following” or “Unfollow” button, depending on what you’re using to view Mastodon. Clicking this changed button lets you unfollow the account if you want to.
However, sometimes the follow button turns into “Pending” or “Cancel Follow” or “Follow Request Sent”, and this means the follow hasn’t actually happened yet.
If the follow hasn’t happened yet, this usually means you’ve tried to follow an account that needs manual approval of followers, and you have to wait for the owner to approve your request. You can tell if an account requires approval as it will have a padlock icon 🔒 on its profile next to the username. (If the account does not have a padlock 🔒 on its profile, then an error may have happened. See below for what to do in this case.)
An account will be more likely to accept your follow request if you fulfil their requirements. Quite often accounts that have follow requests switched on will have criteria for accepting follows mentioned in their profile text (for example many require followers to have posted before, or to have a profile text).
Sometimes the follow request message appears even when the account you’re trying to follow doesn’t have manual approval mode switched on. In this case, the message may be caused by several other things:
If you see that an attempted follow has turned into a follow request but the other account doesn’t have requests switched on, try leaving it for a while as it may just be a temporary glitch.
If that doesn’t help, try cancelling the follow completely, wait for a while and then try clicking follow again, which sometimes helps the follow to go through properly.
If it still doesn’t work, contact your own server admin, and if they can’t help try contacting the admin of the server for the account you’re trying to follow.
No, you don’t see this message if you’ve been blocked by someone.
The message means the account you’re trying to follow probably just have follow requests switched on, and if they don’t then there’s just a technical problem.
If you’re looking for a long list of tips on how to make your account and posts more visible, please click here see the guide to increasing your visibility.
If you’re deciding on a posting schedule, it’s a good idea to wait until you have at least some followers from other servers before you publish your most interesting stuff. Even a handful of followers will give your posts much more visibility across the Fediverse, as you only need one follower from a server to make your posts visible to that entire server. You can find out more about this in the guide to what servers can see.
Due to the way the Fediverse currently works, if you publish a post while you still have zero followers, that post will probably not be visible to anyone except people on your server. If someone is the first person to follow you from their server, they will see your posts from that moment onwards, but there’s generally no backfilling to show them your previous posts.
Once you have one person from a server following you, everyone on that server will be able to see all your future posts from that moment onwards. Even tiny amounts of followers make a big difference to visibility, they are always much better than zero followers.
Build up a following and gradually add a steady stream of interesting posts. Don’t do massive dumps of content before you have any followers.
This applies especially to people who run PeerTube accounts, which often start out with massive uploads of video archives that no one on other servers can see because no one has followed the account yet. They would get a lot more views if they upload the archive gradually as they build up a following.
On Mastodon, the only way to make posts visible to absolutely everyone who ever looks at your profile is to pin the posts on your profile. Pinned posts are backfilled and will become visible to anyone who follows you. You can pin up to five posts at once, and they will all be backfilled. You can also reply to pinned posts, and the replies will be backfilled too.
If a profile looks blank, it may not actually be blank!
Fediverse servers work like this: servers only notice accounts from other servers if someone follows or interacts with them. If no one on your server follows a particular account, and that account is on another server, then that account may appear blank to you.
The reason servers work like this because of resources. If servers had to keep a copy of every post from every user on all the thousands of Fediverse servers in the world, their running costs would become prohibitively expensive (and most of those posts would probably never be read anyway).
The idea of the Fediverse is to let anyone start their own server if they want to, and this process of servers “noticing” accounts helps make that possible.
To check what a blank profile really looks like, go to the profile, click on ︙ and then “Open original page” or “Open in browser”. This should open the profile on its home server, which will show the most up to date version of the profile.
Unfortunately, original pages on other servers are more difficult to interact with. By default your have to enter your username and password each time, though there are ways to make it much easier.
If you pin some of your posts to your profile, for various technical reasons your profile will never appear blank to anyone as these posts will always be visible. You can pin up to five posts on a profile, and these can include attached photos, video and audio, so they’re a great way of introducing your account to potential followers from any server. Click here to find out how to pin posts.
There’s there may be a possible solution to blank profiles on the way called “backfilling”. This would mean as soon as you follow someone your server would automatically check the account for past posts and display some or all of them on your server. With backfilling there would be much less need to fiddle around with original pages etc. At time of writing backfilling is the most popular suggestion on the Mastodon github site, and if you’re comfortable using github you can go and give it a thumbs up ⧉.
The official Mastodon roadmap ⧉ has an item labelled “Explicit controls to fetch more data from origin server”, which seems to mean they would introduce some kind of update button to fetch the latest version of a profile on demand. It’s in the “Planned” section of the roadmap which means they’re working on it. These would be practically very similar to the backfilling mentioned above.
An alternative reason why an active account might look blank is this: if the account has follower requests on (indicated by a padlock 🔒 next to their name), and all its posts are followers-only, then you will not see any posts on their profile until you follow them and your follow request is accepted.
There are tens of thousands of Fediverse servers with millions of users in total, and this amount is growing all the time. There are hundreds of millions of posts going back almost a decade.
However, each server only “notices” posts and profiles that are connected to its members in someway, either through an interaction, or a following, or various other specific situations.
The reason why servers only notice certain posts and profiles is because would be horrifically expensive for every independent server to keep a complete, up-to-date record of every post ever made by every user on every server in all languages. The only people who could afford such a comprehensive system would be megacorporations like Facebook, Google, Twitter etc.
The whole point of the Fediverse is to allow small independent servers to exist as part of a larger network, so that the network is as spread out as possible (click here to find out why this is a good idea). The smallest Fedi server starts from about US$10 a month to run, and this low cost is possible because the server only needs to display posts and shares from people its users follow. Even the largest Fediverse servers are able to operate on a fraction of the budget of a commercial social network because they are only showing posts their users have to see. (If you’re interested, there’s a complete list of what a server can see here.)
If you discover an account that no one on your server has followed or interacted with, it may look totally blank even if it has posted lots of times. This can mislead people into thinking a profile is inactive and not worth following. If you follow a profile you will start seeing all its posts published from that moment onwards, but older posts are not loaded retrospectively.
Also, searches will produce fewer results and threads may look less complete if your server hasn’t noticed accounts related to the topics you searched for.
Yes, this is a good point. One of the main shortcomings on Mastodon and many other Fediverse server types is the lack of “backfilling”.
Backfilling is when an account’s posts are automatically fetched to your server when you follow or view an account’s profile. Without backfilling, profiles can look blank if no one on your server has followed it before. At the moment, the only posts backfilled by Mastodon are pinned posts.
The main thing preventing backfilling from being used has been concern about stress on servers, especially if an account has thousands of past posts to backfill. A possible compromise might be letting servers decide for themselves if they will allow backfilling, and how many posts they are willing to backfill.
If you’re comfortable using Github, you can let the developers of Mastodon know you want some kind of backfilling to be implemented by giving a thumbs up on the relevant issue ⧉, and if you have your own ideas you can contribute to the thread.
Yes! If you’re an ordinary user you can follow and post to groups, which distribute all of their content to everyone in the group no matter which server they are on.
If you’re a server admin, there are ways you can get more results visible on your server, even if your server is small and new.
Well, you could do this, but then you end up back where you started with a server that can be easily bought out by Elon Musk or whoever as soon as it gets popular. It would be entirely missing the point of the Fediverse.
Again, you couuld do this, but then whoever controls that giant relay server would have an unusually large amount of power over what is visible on the Fediverse. It would also be expensive to run. Combining massive expense with centralisation makes it very likely that such a relay server would end up being sold to the highest bidder and start going down the path of “enshittification ⧉“.
Yes! PeerTube automatically backfills all of an account’s videos as soon as an account is followed from a PeerTube server, even if the videos are very old. This works fine, and shows that backfilling can be done on the Fediverse.
Also, as mentioned above, Mastodon does backfill pinned posts already.
If you are searching for something on Mastodon and the Fediverse, you will get different search results depending on which server your account is on. This is because each server sees a slightly different view of the Fediverse.
In general, your server can see the following content:
If a specific post isn’t visible from your server but you know it exists, you can manually force your server to notice it by copying and pasting the post’s web address from its original page on its home server into the search box on your server. This will make the post appear within your server so you can interact with it and search for it just like any other post.
If a specific account isn’t visible from your server but you know it exists, you can manually force your server to notice it by copying and pasting its Fediverse account address into the search box on your server.
If you want your server to notice a lot more posts and accounts in general, ask your server admin if they have considered using a relay service and/or scripts. Modern relay services can be for specific topics so they don’t take up as many resources as general relays. Scripts can be used to show trending posts from other servers or backfill missing posts from profiles and conversations.
Fediverse servers are selective about what they see, because keeping a complete copy of all posts from all other servers regardless of whether they’re needed would be incredibly expensive and wasteful.
The point of Mastodon and the Fediverse is to create a social network where anyone can make their own server, so that the network remains in the ownership of the people and communities that use it. This is possible partly because of the structure, but also partly because the running costs of servers is comparatively low. Fediverse server prices at hosting companies start from about US$8 a month, including full tech support that covers all the technical stuff.
If servers had to notice all content from all other servers, they would become incredibly expensive to run, and only megacorporations like Google or Meta/Facebook would have enough money to do so.
Yes, if the server’s admin decides to defederate from another server. When a server defederates from another server, it can no longer see posts or accounts from the defederated server.
Alternatively, a server admin may instead decide to suspend a specific account on another server, which will make that account and its posts no longer visible on the admin’s server.
If you’re a member of a PeerTube server, it works very differently to most Fediverse servers. When a PeerTube server notices a channel or account from another PeerTube server, it also notices all the videos ever published by that channel or account. This is known as backfilling and at the moment it only happens fully on PeerTube, but there are plans for it to happen more widely.
On Mastodon, if you have posted in a thread or been tagged in it, but you don’t want to take part any more, you can mute the conversation so that you won’t get notifications from it. No one will know you’ve done this, and it will only affect that thread:
If you change your mind, just do the same thing again but select Unmute conversation.
You might also be able to access the Mute conversation option while browsing the thread itself, but for some reason this isn’t as reliable as muting it from the notifications.
If the problems in a thread are limited to a small number of people, you might want to try muting their accounts instead. You can mute people indefinitely or temporarily.
On Mastodon, if you follow someone and you want to see their posts but not their boosts, you can hide just their boosts without blocking or muting them. This doesn’t affect their normal posts, and they have no way of knowing you’re doing it.
Log in on your server’s website, and go to the profile of the person whose boosts you want to hide. Click on the ︙ button and select Hide boosts from. If you change your mind, go back to their profile and select Show boosts from.
This only works on accounts you follow.
If you’re using Mastodon through your server’s website or the web app, you can optionally have it ask you for confirmation before unfollowing, deleting or boosting a post:
The mobile apps may also have similar settings, but it will vary from app to app. Click on your app’s settings page to see if it has these options.
If you add a poll to your post on Mastodon, by default it only allows people to select one option.
However, if you use your server’s website or the Mastodon web app or certain third party apps, you can customise the poll so that it allows people to vote for several options at once.
If you’re using Mastodon through your server’s website, you can choose a poll type by doing the following:
The official apps don’t yet support creating multiple poll types, but you can choose poll types on some third party apps.
Third party app interfaces are very varied, but for example Ice Cubes for iPhone/iPad has a menu when you’re creating a poll that lets you choose between “One Vote” or “Multiple Votes”.
You can also edit the poll type after you have posted the poll, but this will reset all of the votes to zero (without any warning) when you publish the edit. Also, editing any of the poll texts causes this same reset to zero.
Most people on the Fediverse are on a standard Mastodon server, which has a 500 character limit for posts and a four option limit for polls. However, sometimes you’ll see people with posts that are much longer than 500 characters. By default Mastodon doesn’t allow admins to adjust character limits, so how is this possible?
There are three ways that someone’s posting limit might be larger than 500 characters:
There’s nothing in the admin interface of standard Mastodon that allows character limits to be adjusted. However, Mastodon is free open source software and anyone can customise it to suit their own needs. This means admins with the right technical knowledge can adjust the Mastodon code to have a different character limit.
There are many pre-customised versions of Mastodon, often with significantly more features for admins and members. Pre-customised versions of open source software are called “forks”. The most popular forks of Mastodon are Glitch ⧉ and Hometown ⧉, which add lots of extra features including the ability for admins to easily adjust their server’s character limit.
Not all of the posts you see on your timelines are from Mastodon. There are many other Fediverse server types that aren’t Mastodon, and these other servers may have much larger character limits for posts. Some like Friendica or WordPress have no limits at all!
Standard Mastodon will show long posts but they will be automatically truncated with a Read More link at the bottom, so that timelines remain easy to browse. You can view the full version of a truncated post by clicking on Read More.
You can ask them, but bear in mind that standard Mastodon (aka “Vanilla Mastodon”) does not have any options in its admin interface to adjust character limits. The only way they can adjust it is by using one of the unofficial methods listed above, and not all admins can use these options because they may require additional technical skill and/or resources.
The lead developer of Mastodon gave the following explanation in 2017 ⧉:
I have denied such patches in the past. If somebody wants to hack it in, they may do so, but I don’t want to encourage it. I feel like (Mastodon’s) UX is designed, visually and behaviourally, around a certain number of characters, and deviations have a negative impact on it. For example, I want people to pick their Mastodon based on, for example, the policies, or the theme, but I want the base level of functionality to be the same so it doesn’t go into the choice.
Of course nothing is set in stone. If you’re comfortable using Github you can give a thumbs up in the relevant issue ⧉.
By default, Mastodon servers’ websites use a simple single column interface.
However, if you’re using the website through a computer (or a tablet/phone in horizontal mode) there is also an optional multicolumn interface you can use instead. Here’s how to activate it:
If you’re already in multicolumn and you want to go back to the normal single column interface, here’s how to do it:
When you first use it, the advanced web interface only contains four columns with one of these columns dedicated to whatever you last selected. Every time you select something, it replaces the contents of this fourth column.
However, if you want to keep a column permanently visible you can pin it, and the pinned column will be added to your previous columns.
When you pin a column, it expands the interface sideways, and some people have lots of pinned columns. Pinning is well suited to widescreen monitors, and you can scroll the interface sideways to see any columns that don’t fit on the screen.
You can move a column left or right by clicking the ⚙️ cog icon in its top right corner and then clicking one of the < or > buttons to move the column. These buttons are next to the Unpin option.
Any column with a ⚙️ cog icon in the top right can be pinned or un-pinned, which includes hashtag searches, all types of timeline, private mentions (DMs), Lists, Bookmarks, Favourites etc.
If you pin a hashtag search and then click the pinned column’s ⚙️ cog icon again, you will see some additional options which let you combine hashtag searches into the same column with special filters:
You can’t pin an account’s profile page directly, but you can pin particular accounts (or combinations of accounts) as new columns by using Mastodon’s Lists feature:
If timelines are updating too quickly, you can switch Mastodon to “slow mode” so that columns only update when you click at the top of them:
Slow mode also works on Mastodon’s single column interface.
If you prefer using just your keyboard, the Mastodon web interface can optionally be controlled almost entirely through key commands, click here to see the section on hotkeys for a complete list. These hotkeys also include some commands that only work in Advanced mode.
If you prefer the normal control method using the mouse, that works fine too.
No. There is a totally different, totally separate feature also called pinning where you can pin posts to your profile page. This has nothing to do with pinning columns, they just have a similar name.
If your server is running an older version of the Mastodon software, it may show a slider icon instead of a ⚙️ cog icon. They do exactly the same thing, they just look different.
The original website version of Mastodon from 2016 used the multicolumn interface, but while some enjoyed it others found it confusing and overwhelming. Eventually a simpler single column interface was introduced, and single column became the default. The multicolumn interface was renamed “advanced” and made available as an optional mode in settings.
If you’re running a Mastodon account that isn’t monitored by a human, it’s considered polite to mark it as an automated account (also known as a bot).
Bad bots are discouraged and blocked, good bots are encouraged and followed.
Good bot accounts can be extremely useful. For example, some bots post sports results or weather alerts, which are exactly the kind of thing people might appreciate seeing in their feeds at any time of day or night. This kind of account would be difficult for a human to maintain 24 hours a day.
Bots can also be entertaining, with some bots running games or posting amusing content.
Some bots can interact, yes. When there is interaction, it is usually automated, hence the “Automated” label. Vote Chess ⧉ is a nice interactive account, it lets people play chess against a computer by voting for the next move (you can follow it at the address @VoteChess@botsin.space).
Also, sometimes the bot’s human maintainer will post via the bot’s account and reply as well. However, on automated accounts this is rare, and the assumption should be that there is no one monitoring the account.
Have a look at the Bots category over on Fedi.Directory ⧉.
The bad bots you sometimes hear about are where someone has automated an account to do something nasty or anti-social such as posting spam. Bad bots tend to be rare on the Fediverse, and would usually be blocked pretty quickly once the nastiness is reported.
If you see an account labelled “Automated”, that is actually the sign of a good bot, because it’s the owner of the bot who chose to label it as such. Another good sign is if the bot’s creator has included a link to their own account on the bot’s profile page.
Bad bots usually try to disguise the fact they are bots, and don’t use the “Automated” label.
RSS feeds are simple, easy-to-use feeds of content from the internet, such as news articles, videos and podcasts. You can use RSS apps to follow Mastodon accounts, and use Mastodon accounts to follow RSS feeds.
RSS is basically just a special kind of internet address that tells an RSS app where to find content. The apps used to follow RSS feeds are often called “feed readers” or “news readers”. When you enter an RSS address into an RSS app, the posts made by that address are shown in a chronological list.
RSS feeds can work for all kinds of content including blogs, news sites, podcasts etc. (Most podcast apps are powered by RSS, even if they don’t publicly state this.)
All Mastodon accounts have an RSS address which can be followed from RSS apps:
For example, the RSS feed for the FediTips account is https://social.growyourown.services/@FediTips.rss ⧉.
Note that the RSS feed of a Mastodon account only shows posts with public visibility, you will not see replies or posts with other visibilities.
You can also now do this the other way around, and follow RSS feeds from your Mastodon account, thanks to a service called RSS Parrot ⧉:
This method works for any Fediverse platform that supports microblogging, including Mastodon and many other Fedi platforms.
You can follow any PeerTube accounts or channel through RSS apps:
This feed will deliver embedded videos to your feed reader and you can watch them there.
The Fediverse platform Friendica has probably the best RSS support on the Fediverse, including a built-in feed reader which doesn’t need any third party services or apps.
To follow an RSS feed in Friendica:
Friendica also lets you turn RSS feeds into Fediverse accounts that people can follow from other Fediverse platforms.
You can embed posts from Mastodon on your own website, blog or other platform that lets you post HTML code. Here’s how to do it:
Embedding means the post itself will be displayed on the website, and all the post’s interactive elements such as links, images, video, audio etc can be clicked on and will work. For example, news website The Verge embedded a post from Mastodon in this story ⧉.
If you’re using the block editor in WordPress, don’t use WordPress’s “Embed” block. Instead, use WordPress’s “Custom HTML” block and paste Mastodon’s HTML embedding code there.
Alternatively, if you’re editing the page’s code you can paste the embedding code directly.
Embedding a post means the post itself is displayed, and any interactive elements such as links, video, audio or images can be clicked on. Screenshots are just pictures of a post and cannot be interacted with.
If a post has a restricted visibility, it cannot be embedded because the creator of the post doesn’t want it to be widely seen. You can only embed posts with a public visibility.
The post you embedded may be from a different type of Fediverse server. Embedding shows the post in the format used on its own server rather than your server.
Timelines on Mastodon servers show posts from all across the Fediverse. Some of these posts are from other Mastodon servers, but some are from different kinds of servers. For the sake of making timelines easy to read, your Mastodon server will display all posts in the same Mastodon format, but that’s not necessarily how they appear on their own server. If you embed a post from a different kind of server, it will look different when you embed it.
If you’re using Mastodon through your server’s website on a computer, you can control it almost entirely through your keyboard. Particular keys will carry out particular functions, and you can type emoji too.
Hotkeys are always on, press shift + ? (or just ? on some keyboard layouts) to see a complete guide to which keys do what.
Note that some of these keys are only useful in the advanced web interface (multicolumn) mode, but most of them can be used with the default single column mode.
For your convenience, here’s the complete list:
| r | Reply to post |
| ctrl+enter | Publish post |
| m | Mention author |
| p | Open author’s profile |
| f | Favourite post |
| b | Boost post |
| enter, o | Open post |

If you’re using Mastodon on a computer, you can type emoji directly with your keyboard.
Just type : (colon) and a keyword without a space. A dropdown menu will appear with the top five matching emoji, and you can pick one with the arrow keys. For example :sun will bring up the top five emoji matching the keyword “sun”.
If there are more than five matches for a keyword, they will not all appear on the dropdown. If so, you’ll need to search for them from the picker icon 😂 in the top right corner of the editing box.
The keywords are based on the alt text of an emoji. If you’re wondering how to search for a particular emoji in future, find it in the picker and then hover your mouse over it. The alt text will appear, and you will be able to use this keyword to bring the emoji up using your keyboard.
This tip no longer works, I’m leaving this page here in case anyone follows a link to it, but it’s no longer listed on the front page.
On older versions of Mastodon you could see an account’s first page of posts by adding ?min_id=0 to the end of its profile URL. This no longer seems to work on current versions of Mastodon.
Remote following or remote interaction is where you go to the website of a different Fediverse server which you’re not a member of, and try to follow an account or interact with a post there. By default it will ask you the name of your server, because it’s asking your own server to confirm who you are. It will then take you to your own server’s website where you can sign in and the interaction can happen.
This is obviously pretty cumbersome, especially if you’re browsing the websites of many different servers as they will each ask you for your server separately. But there is an easier way:
Yes! For example you can copy and paste the web address of a PeerTube video or Pixelfed photo into the search box on a Mastodon server, and the video or photo will appear within Mastodon. By the way, it will look like a Mastodon post if you paste the address into Mastodon, but you can see its true form by looking at its original page.
Remote following is meant more as a method of last resort, rather than the main way of using the Fediverse. You’ll find it a lot easier to follow people from other servers within your own server’s interface, and once your server has noticed an account or post you will be able to find it again by searching for it within your own server.
The latest versions of a lot of apps do recognise Mastodon and other Fediverse links, and do the copy-pasting for you seamlessly behind the scenes. That’s why you may see a brief delay after clicking a link, while the app does the copy-pasting and presents you with the post or profile within the app itself.
However, this automation doesn’t always work. If your app fails to recognise a link as leading to a Mastodon/Fediverse server, that’s when it shows you the server’s website and you need to manually copy-paste it back into the app’s search box.
Every account and post on the Fediverse has an “original page” on the server that the account or post is hosted on. The original page shows the latest and most complete version of a profile or post. They’re called original pages because they are the original versions of posts and profiles that are federated to other servers.
If you’re using the website or web app:
If you’re using an app store app:
Once the page is open, the original page’s web address will be visible in the browser’s address bar at the top.
You can also copy original page links for posts without actually opening them in the browser.
If you’re using the website or web app:
If you’re using an app store app:
The main reason for looking at the original page is to see the latest and most complete version. However, you can also use original pages to do many useful things, with some examples given below.
If no one on your server has interacted with a profile before, it may appear blank. You can open the profile’s original page to check if it really is blank.
Sometimes a profile’s follows and followers may not be visible to your server, or it may be incomplete. If you go to the original page and click on the follows and follower lists there, you will see their complete versions. (However, note that some people deliberately keep their follows and followers lists hidden for privacy reasons.)
If there’s a profile or post that you can’t find by searching on your server, but it does show up in results on search engines such as Duckduckgo, Google etc, you can use these pages to force your server to notice people and posts it hadn’t noticed before, including pages from other types of Fediverse server. Just copy and paste the page’s web address into the search box on Mastodon, and it will make that post or profile appear within your own server where you will be able to interact with it directly.
Original pages aren’t just on Mastodon, they work with any Fediverse server type. For example if you know the web address of a PeerTube video or Pixelfed photo, you can paste it into the search box on Mastodon and the video or photo will appear within Mastodon. You will then be able to interact with it as if it was a Mastodon post.
The process of copying and pasting web addresses works in a very similar way to account addresses.
Original pages are really useful if you want to share a profile or post with people outside the Fediverse, as you don’t have to be logged in to see them. Just give people the original page’s web address and it will open in any browser, they don’t have to log in or be a member.

You can automatically crosspost on Mastodon and other social networks using third party services. Crossposting means you can post the same content on several social networks at once.
This can be controversial if you’re just posting to Mastodon without interacting on Mastodon at all. Some servers specifically ban such “zombie accounts”.
Professional paid crossposting services such as Buffer ⧉ and Publer ⧉ offer crossposting services compatible with many social networks including Mastodon.
Yes! Your followers will want to reply to your social media posts, and it is a good idea to react to what they say.
However, if it isn’t possible for you to monitor your accounts, please mark them as automated through Mastodon. This lets people know that you’re posting in one direction only.
On Mastodon, you can customise your notifications to adjust what triggers a notification to appear and what kind of notification it provides. The notification options you have depend on what you are using to access Mastodon.
If you’re using Mastodon through your server’s website or web app, you will have the largest number of options for customising your notifications.
As well as customising how notifications are displayed, this menu also lets you clear notifications away. Be careful if you use this, as once the notifications are cleared you cannot get them back. There’s no real need to clear them, but some people prefer it.
The options for customisation of Mastodon notifications tend to be more limited on the app store apps.
Email notifications on Mastodon are a totally separate system that happens to have a similar name. To adjust your email notifications:
If you want a clickable website link within a post or on a profile on Mastodon, remember to include https:// at the beginning when you’re writing it. This tells the server that you want the link to be clickable.
Twitter automatically changes anything with a dot in the middle into a clickable link, but this doesn’t happen on the Fediverse because some people want to include dots without making clickable links.
Yes! As well as website links, you can also use many other kinds of links. All of these will work as clickable links on Mastodon: https://, http://, gemini://, dat://, dweb://, gopher://, ipfs:// and ssb://
Fediverse addresses have two parts, the username and the server name.
By default, Mastodon and most other Fedi server types hide the server part of the address within posts so that they are easier to read. All you will see in conversations is the first part of the address, so you would see @john even if the full address is @john@example.com. (This is similar to how real life conversations often just use a person’s first name.)
This means that it’s a good idea to choose something distinctive for a username, because in posts people will often just see the username on its own.
An account with the address @MarvellousWidgets@example.com, would look like @MarvellousWidgets in conversations. People can refer to it in discussions and it’s still clear who is being talked about: “Have you seen the latest release from @MarvellousWidgets?”
If it had a more generic username such as @software@example.com, all that people would see of its address in posts would be @software, and it’s not clear who is being talked about. A discussion using it would look like this: “Have you seen the latest release from @software?”. People would have to click on the username each time to find out who they are, because so many other accounts have a similar username.
Yes and no. The full address with a custom domain is indeed very distinctive, but because the domain is hidden by default in discussions, it is still important to choose a distinctive username, as this is what most people see most of the time.
Some Fediverse server types allow you to use . in usernames while others (including Mastodon) don’t allow it. People will not be able to follow you from Mastodon if you use a . in your username, so it’s safest just to avoid using . in usernames.
If your username is very short, it is physically more difficult for people to click on it or tap it. Try to use at least four or five letters, preferably more.
Mastodon etc will automatically show accounts’ full account addresses if two accounts with the same username are mentioned in the same post. This is also similar to real life conversations: if you were talking about two people called John in the same conversation, you might mention their surnames so that people know which John you’re referring to.
Account addresses can be very long, depending on the domain name used by the account’s server. It can be quite hard to read a post where full addresses are used all the time. Just showing the username makes posts a lot more readable.
Just click on the username, that will take you to the user’s profile page which includes their full and unique account address.
The “Lists” feature lets you create mini-timelines that show posts from selected accounts you already follow. You can also optionally hide listed accounts’ posts from your main timeline, and just browse them on your Lists.
If your main timeline is getting a bit crowded from following so many people, you can add accounts to Lists and then hide them from your main timeline (see instructions further down the page).
You might also like having themed Lists to browse. For example, you could create Lists which just show posts from artists you follow, or just news accounts, or just sports, or whatever kind of themes you want. You can then click on different themed lists when you’re in the mood for those particular topics.
Or maybe you want to do both of these things!
You can create and use Lists on your server’s website, on the Mastodon web app and on some third party Mastodon apps such as Tusky for Android or Mona ⧉ for iPhone/iPad.
To create a list through the web version of Mastodon:
…and that’s it, you’ve made your first List. You can repeat the process to create more Lists.
For privacy reasons, you can only add accounts that you follow to your Lists. So, the easiest way to add accounts to your Lists is to scroll your profile’s following list.
You can add more new Lists and more accounts to existing Lists by repeating these steps.
Third party apps may have slightly different interfaces for editing Lists, but it’s the same feature and handles the same Lists.
Yes, this is one of the main purposes of Lists! You can hide posts on a particular List from appearing on your Home timeline, here is how to do it:
This means you can have lists that are entirely separate from your Home timeline.
Yes, you are still following them. You’re viewing them via a List rather than your main timeline, but it’s still a follow.
If you’re using your server’s website or web app, you can view Lists by clicking the Lists icon on the right of the screen (three horizontal lines with three dots and a box around them).
If you’re using the official apps, go to your main timeline (the one that appears when you first open the app) and click on the Following link at the top, then select Lists and then the List you want to view.
If you’re using third party apps, they will have various interfaces for viewing Lists.
Don’t worry if a List looks empty. Lists always start out empty as they don’t show posts from before the List was created. Once the accounts on the List start publishing newer posts, you will start seeing these new posts appear on the List.
To edit or delete an existing List, click on the List’s name to open it and then click on the ⚙️ icon in the top right corner of the List. This editor also includes a search box for searching accounts you follow, if you prefer to add accounts to your List that way.
The official apps sort of support Lists, but their support isn’t as good as the web and selected third party apps.
The official Android Mastodon app lets you view Lists and add accounts to Lists, but doesn’t let you create Lists. To add a profile to a List on the Android app, click ︙in the top right corner and then Add to list…
The official iPhone/iPad Mastodon app lets you view lists but not create them or add to them.
The following requirement is for the sake of safety and privacy. On some social networks such as Twitter, List-style features have been misused by trolls and bullies to make lists of potential victims.
On Mastodon, the follow requirement gives people more control over being listed. If an account has follow requests activated, it lets them control whose Lists they may end up on, and if an account blocks someone that also prevents them being added to that person’s Lists.
Yes, you see everything you would see from that account on your Home timeline.
No, not at the moment. However, this is a very popular suggestion and if you’re comfortable using Github you can vote for this option by giving a thumbs up on the relevant issue ⧉.
As many as you want.
No, they’re just for your personal use.
Edit list – Lets you change the list’s name and add or remove accounts from the list
Delete list – Deletes the list
Hide these posts from home – With this option switched on, posts that appear on your lists will not appear in your Home timeline
Show replies to no one – You will not see any replies in your list, only new posts by the accounts on the list
Show replies to members of the list – You will only see replies by accounts on the list to other accounts on the list, and new posts by accounts on the list
Show replies to any followed user – You will see replies by accounts on the list to accounts that you follow, and new posts by accounts on the list
Yes. Lists are now available to export and import as part of the account transfer process.
Yes, you can use Mastodon’s advanced web interface to view Lists and then pin them so that you see several Lists alongside each other. To pin a List:
First of all, it’s worth saying that most people do not need multiple accounts. The Fediverse is designed in such a way that people on different servers can interact seamlessly, as if they were all on one network. For most people one account is enough, because it lets you interact with people on the whole network. However, there are situations where having more than one account is useful.
Lots of possible reasons:
“Alt accounts” or “alts” just mean alternative accounts owned by the same person. They may be permanent or temporary.
Yes, all the official and third party apps support being logged into multiple accounts simultaneously, and you can also be signed into several accounts at once on the web browser and web apps.
Apps normally have an account switching button in the corner of the screen which you can press to select which account you want to use. Alternatively, you can use several different apps if you prefer. The official Mastodon apps have a switcher in the bottom right corner of the screen, hold it down to add an account or switch between accounts.
If you’re using accounts through the web browser and your accounts are on different servers, you can be signed into multiple servers at once and switch between them by keeping each one open in a separate tab. You can use the same email address when signing up for accounts on different servers.
If you’re going to have multiple accounts, it’s highly recommended that you sign up on different servers! Having accounts on several different servers brings very significant advantages:
It’s the independence of each server that makes it good to have accounts on separate servers. It means any kind of problem that hits one server will not affect your other accounts.
Yes, you can, but it will be putting all your eggs in one basket. If that server goes down, it means you lose all access to the Fediverse. It also makes it more difficult to log in on web browsers and web apps, as you will probably have to keep signing in and out.
A common way to promote your other accounts is to mention them in your account profile page. It’s also highly recommended that you follow your other accounts, so that their content will federate more widely.
If you run an account that needs to stay operating as reliably as possible (for example if it’s giving out important info), making a backup account on a different server is a good idea. If your main account’s server goes down, you will be able to switch to your backup account to post.
When you choose a server for your backup account it might be worth checking with the admin that they are okay with it, as some admins delete inactive accounts and your backup is likely to stay inactive for long periods. Also, it’s important that the backup account’s server isn’t owned or run by the same people as your main server.
After you’ve set up your backup account, tell your followers about it and encourage them to follow it. Make clear that you will only post from your backup if your main account goes down, so it won’t be any extra strain on their timelines.
This is a bit technical, but there’s a little-known feature on Mastodon called “Authorized Fetch”, aka “Secure Mode”. By default it is switched off as it uses more resources and can cause compatibility problems with servers running older software.
When it is switched on, it makes all blocks more effective, including both server-level and user-level blocks. This empowers users to fight abusers and trolls more effectively, and makes the server’s own blocks more powerful too.
Posts using follower-only or mentions-only visibilities are already protected from unauthorised interaction. Authorized Fetch only makes a difference on public or unlisted posts. If you never use public or unlisted posts, you don’t need Authorized Fetch.
Please see the post visibility guide for all the kinds of visibilities that a post can be, and how to set your defaults.
There’s an official technical description of Authorized Fetch here ⧉ and a detailed unofficial article here ⧉ which might be useful.
Only server admins can activate it, so if you’re not an admin you’ll need to contact your server’s admin and ask them to do this.
The latest version of Mastodon includes controls in the graphical interface for activating it:
On some managed hosting services this option may be greyed out. If so, ask the managed hosting company to switch it on for you.
Authorized Fetch uses more server resources as the server has to do a lot more checks for each post to prevent unauthorised interactions. However, the costs of these extra resources may be worth it for the extra level of user safety the feature brings.
No, not nowadays. It consumes more resources, but not a huge amount more. There also don’t seem to be compatibility problems any more, as software has been updated to take account of servers with this option activated.
No, nothing can stop scraping of public posts on a public website. However, scraping a website and copying its contents is not the same thing as interacting directly with a thread on a social network.
Authorized Fetch is an official feature of Mastodon and it should work fine when federating with servers that are running Mastodon 3.0.0 or higher. It should also work with GoToSocial (which uses Authorized Fetch by default), Pixelfed, PeerTube and most other Fediverse server types.
No. Mastodon isn’t E2EE. Some work has been done ⧉ on building an encrypted messaging system into Mastodon, but it isn’t finished yet.
In theory, the owner of your server could read at your DMs in the server’s database. However, it’s not as simple as that in practice.
An admin would need a certain level of technical skill, as there is no way to view DMs in Mastodon’s admin interface. The server owner would have to manually look through their server’s database directly to read a DM, and bypass Mastodon’s admin interface completely. It’s not something they could do casually.
Social networks typically don’t encrypt messages by default. For example, on Twitter/X all DMs and posts are visible to moderators.
No, they would need direct access to your server’s database, which is restricted to the server owner and their hosting provider.
If you want to send something sensitive, the best option is to use a dedicated messaging system with end-to-end encryption.
There’s a very popular encrypted messaging system called XMPP (also known as Jabber). XMPP is structured like Mastodon, with lots of connected servers, but it is designed entirely for private messaging and calling. There’s a website to help non-technical people sign up on existing servers at JoinJabber.org ⧉ and there’s a managed hosting service to help non-technical people set up their own server at Snikket.org ⧉.
No. XMPP is designed entirely for messaging, calling and real time chatting. It isn’t intended as a social network, and doesn’t use Fediverse protocols like ActivityPub. However, the server structure of XMPP is very similar to Mastodon and has the same advantages, which is why it’s recommended on this website.
Some Fediverse server admins also run XMPP servers too. If you’re happy with how your Fediverse server is run, it might be worth asking your server admin if they have an XMPP server too.
Modern XMPP apps use a standard called OMEMO for end-to-end encryption. As long as everyone taking part in a conversation has the OMEMO feature switched on, then the conversation will be encrypted. If you’re unsure, you should be able to find OMEMO in your XMPP app’s settings page, and you can check which XMPP apps have OMEMO-compatibility at the Are we OMEMO yet? ⧉ website.
XMPP and Jabber are the same thing. “Jabber” was the original name, but unfortunately a commercial company bought the trademark for it. A new name was required and it was decided to use “XMPP” officially, though unofficially many people still call it Jabber as it’s easier to remember.
No one controls it, it’s decentralised and federated. The XMPP network is made up of many indpendent servers that talk to each other.
XMPP is a free open standard maintained by the non-profit XMPP Standards Foundation ⧉. Anyone can use the XMPP standard on their server or app, and each server and app is totally independent.
To keep your Mastodon account extra secure, you can use a feature called “Two Factor Authentication”, also known as “2FA”. When you have 2FA activated, even if someone finds out your password they still cannot log into your account.
2FA usually works through a special app on your phone, tablet or computer which constantly generates special pass codes, often in the form of six random numbers. These codes are linked to your account, and only your app will generate codes that match your account.
When you want to log into your account, as well as your password Mastodon will also ask you for your 2FA code, which you can find out from your app. It will then log you in.
There are many 2FA apps in all app stores, for example Aegis and 2FAS are popular 2FA apps. Apple’s keychain also includes 2FA support. The technical name for these apps is “TOTP” or “Authenticator”.
After you’ve activated 2FA, the next time you log in on Mastodon it will ask your password and then ask your 2FA code. Go to the app and find the code, then type this into Mastodon.
No. You only need to use a 2FA code when you log in, so if you stay logged in it won’t ask for the 2FA code.
No! You can continue to use any device you want even if you have 2FA activated. The 2FA app is only there to provide codes, it doesn’t know or care where you type them in. You can use the 2FA codes when logging in on any device such as computers, tablets or even other phones.
It doesn’t matter, because the current 2FA code changes so frequently. Most people set it to change every few minutes or even every 30 seconds. If someone sees your current 2FA code, it will soon change to something else anyway and the old code will be useless to them.
The only code you need to keep secret is the 2FA’s backup code, which you should print out and put in a safe place. This backup code gives you access to your account if the 2FA app stops working for some reason.
That’s what the backup codes are for, and why you need to keep them in a safe place. If you lose access to your 2FA app for any reason, you can use the backup codes to access your account and switch off 2FA.
It depends on the app, but probably not. Even when your phone is unlocked, most 2FA apps are still locked by default. To access the app’s codes after your phone is unlocked, you still need to type your phone’s unlock code again, or use fingerprint or facial recognition again.
Setting up 2FA is slightly tricky, and it will require you to keep a permanent copy of a special code in a safe place, preferably printed out and kept at home with your other important documents. This special code lets you access your account if you lose access to your 2FA app. If you’re not technically minded, you might want to get help from a trusted friend or relative in setting it up. Make sure they are people you trust, as the backup code would allow them access to your account.
However, after it has been set up, 2FA is extremely easy to use: the 2FA app displays a code and you simply type this in when Mastodon asks you to. It’s very simple and becomes second nature quickly.
No. 2FA apps have no awareness of anything you’re doing.
The apps just passively display a list of security codes generated from the current time and your unique account keys. It doesn’t send any data anywhere, the code generation happens entirely offline on your own phone or computer. The apps have no idea if you’re even using the codes.
At a technical level, 2FA apps are essentially just very elaborate clocks, but instead of displaying the time they display ever-changing access codes. Your account’s server also knows what time it is, and that’s how it knows whether your 2FA access code matches up with what it should be.
It’s not just Mastodon! Most major online services nowadays have an option to activate 2FA. For example most email providers include 2FA support, and using it works just like logging in on Mastodon.
You can use the same app to generate all your codes. Each service uses a different code, and your app will generate a list of different codes if you use it on many services.
Yes! Mastodon’s two factor authentication settings page also includes a section for adding security keys, just click on Security Keys 🔑 Add and follow the instructions. The security key section appears after you have activated a 2FA authenticator app.
If you have an official website, the most straightforward way to verify your identity on Mastodon is to link to your Mastodon profile from that official website. If you include a special piece of HTML code in this link, it will make your website address turn green on your Mastdon profile and people will instantly know that you are the owner of (or professionally connected to) that website. If people already trust your website to be official, then by extension they can trust your account to be who it says it is.
Alternatively, if you’re really keen, you can also create an official Fediverse server based on the web address of your official website. This is, for example, how the European Union has verified all its official accounts on the Fediverse.
On Mastodon, you can create a special verified website link on your profile which turns green. This means anyone browsing your profile will immediately know you’re verified as the owner of the website:
After you’ve done all this in the correct order, you should see a link to your official website on your Mastodon profile, which will turn green with a green tick next to it to verify you are the site’s owner. If you have any problems, see the troubleshooting section below.
This can also be used to verify specific pages on a website, for example if you’re listed as a staff member on an organisation’s website. As long as the creator of the website is willing to add the special verification code, you can verify the link.
If you’re really keen, the most watertight way to verify your identity is to make your own Fediverse server as a subdomain of your official website. This is what the European Union did when they made their own Mastodon server ⧉. Because the European Union’s official website is well known as being at europa.eu, and their servers are all subdomains of europa.eu, it means all the accounts on their servers can be trusted as being official EU Fediverse accounts. Making your own server on a subdomain is much easier and cheaper than you think.
Don’t panic, there are things you can do:
Also, note that each server on the Fedi verfies addresses independently and at their own pace. It is possible that people on other servers may see your address turn green before you do.
If you can’t get the normal link code to work for verification, you can instead insert this code into your site’s front page’s header:
<link href="https://yourserver/@yourusername" rel="me">Substitute your profile page’s URL for the example in the code, but leave it otherwise intact.
