Change your address, add a second name, update your email.
Everything about your name lives under Profile → Metadata.
- Username — your address. Changing it moves your page; the old address stops working. It needs 2 to 20 characters and must not be taken or reserved.
- Alias — a second name that opens the same page. Useful for a shorter address or a name you are known by elsewhere.
- Email — where sign-in and security mail goes. Changing it asks for your current password, the new address has to be confirmed from the mail we send to it, and the old one is told.
Your UID (#1, #2, …) is given in signup order. It only changes if you take a different one from the marketplace.
