Here’s how to alter the email address for your account on Mastodon:
- Sign in on your server’s website or web app
- If you’re on a computer click ⚙️ Preferences. If you’re on mobile click ☰ in the bottom right and then ⚙️ Preferences.
- If you’re on a computer click Account on the left of the screen. If you’re on mobile click ☰ in the top right and then click Account on the menu that appears (you may need to scroll down the screen to see the full menu on some devices).
- Replace your old email address with the new email address, and enter your current password in the Current password box.
- Click the Save Changes button
- Your server will send you a confirmation email. Go to it in your email app and click on the confirmation link. (You need to do this last step for the change to actually happen.)
