Steps to change display name
To update your Roblox username, follow these steps:
On the main Roblox page, click the gear icon in the upper-right corner of the screen and select “Settings.” On your Settings page, click the edit button (which looks like a pencil on a sheet of paper) beside your username. In order to change your username, you’ll need to have a verified email address as well as 1,000 Robux.
On Roblox, you can change your account's username in the account settings. It costs Robux to make this change. However your Display Name is a free option to change how your name appears in an experience or game.
Log into your account (If you can't log in, try these steps for recovering your password .)
A list of previous usernames can be found on the Account Settings and Profile pages, along with People search. You can change back to a previous username, using the above method, which also costs Robux.
A ROBLOX Username is the associated name with your account when you created it. This is required to login to your account, as well being the unique identifier of your account. No two players can have the same Username, and as such, is completely unique.
Changing your username on ROBLOX is an easy, but expensive process. Changing to a new Username requires a cost of 1000 Robux to change, so make sure you’re willing to part with that Robux in order to amend your name.
You can change your Display Name for free, once every seven days. This is how other players see you in-game and isn’t unique to one player. This allows for players to be seen as their desired name, without incurring the costs like Usernames do.
