1. First, make sure you’re signed in to your BBC account.
2. Then, on any BBC website, click the “Your account” icon at the top of the page. (If you’ve got a display name, it’ll show your display name, not “Your account”). It’s in the navigation bar, near your web browser’s address bar.
3. Choose “Settings” and you’ll be taken to your personal details.
4. On the “Personal details” screen, click “Edit” next to your username and enter a new one. You'll need to enter your password so we know it's you.
5. Then click "Save and continue".
6. Remember to use your new username the next time you sign in to the BBC. If you forget your username, unfortunately you won't be able to sign in. Instead you’ll need to register for a new BBC account. Be sure to remember your username this time.
Bear in mind...
