Although you can’t directly change your username, there is a workaround:
You can’t have two Fedora Account System accounts with the same email address. However, if changing your username is important to you, you can:
- Log off from Fedora Discussion.
- Log in to Fedora Accounts and set a new email address for your existing account.
- File a ticket with Fedora Infrastructure requesting that the old account (the one you’re using to file the request!) be deactivated, noting that you’re moving to a new name.
- Log off, and then create a new Fedora Account with your original email address.
- Log in here with that new Fedora Account.
- Discourse will magically notice that the emails match, and merge the two accounts here.
