To change your username on Roblox for free, first log into your Roblox account. Next, visit the Roblox Support page. You’ll need to fill out the support form with some details.
Start by entering your email address, which will be used for the response. Then, select the device you are using. Choose a help category that suits your situation, like “User Safety Concern” or “Billing and Payments”.
In the description box, explain why you need the username change. For example, you can mention that your username contains “YT” and you wish to avoid account termination. After filling out the form, click submit.
Wait for an email response from Roblox support. They usually reply by the end of the day. If your reason is valid, they may offer you a free username change.
This method works if you provide a good reason for the change. Follow these steps carefully, and you might get your new username without spending any money.
