Quick Scoop: You can’t change your Roblox Studio username inside Studio itself, because Roblox uses the account username tied to your Roblox account, not a separate Studio name. To change it, go to your Roblox account settings, open Account Info , click the pencil/edit icon next to your username, enter the new name and password, and confirm the purchase.

What to do

  1. Sign in to your Roblox account.
  2. Open Settings.
  3. Select Account Info.
  4. Click Change Username or the pencil icon.
  5. Enter your new username and current password.
  6. Pay the required Robux and confirm.

Important detail

Roblox says username changes cost Robux, while your Display Name is a separate free option that changes how your name appears to others. If you only want a visible name change, Display Name is usually the easier route.

In Studio

If you mean the name shown in a Roblox Studio project, that is usually the place you’re editing a game or place, not your account username. Your account username change still has to be done on Roblox account settings, then it will carry over everywhere you sign in.

Costs and limits

Roblox’s help page confirms the username change is a paid account action, and recent guides commonly describe it as 1,000 Robux. The exact in-app flow may vary a bit by device, but the account settings path is the same.
