Can I change my username?
No. Once you create your MovieStarPlanet account, your username can’t be changed.
Usernames stay connected to the same account for safety and account-management reasons. They’re also unique, so no other player can use yours.
If you want a different username, you’ll need to create a new account and choose a new one during sign-up.
Choose carefully—you won’t be able to change it later.
