To get or change a Roblox Display Name, you should first log in to your Account Info page under Settings, then select the edit button next to the Display Name entry above your Username.

To change your Roblox username login to your account and go to the settings section. In a browser this is represented by the gear icon in the upper-right corner.

ROBLOX allows you to change this username, as well as your Display Name. It’s important to note that there are different rules and applications of both Usernames and Display Names.
