roblox username says it is already in use

This also has happened to me. It could be as simple as someone already having the name and maybe their roblox account had been disabled. I had changed my name on xbox and I think that’s what triggered my problem. I had to create a whole new account because
I couldn’t find a solution.

Hello Connor,

If you still have access to Roblox on Xbox it shows the account username that’s linked to your Xbox profile in settings while in game. Username/Email/Phone can be used to sign in for Roblox. If you can’t remember the password a email or phone number is required to reset the password. The Roblox website will have more information on password resetting and account recovery.

Hi, I don’t know if I’m doing this right. Can you explain what you mean when you said Xbox gamertag credentials. Like my password to login into Roblox would be my Microsoft account password as I remember both that and the username to it but, not the password to my Roblox account. I don’t have a pc so, I tried to login into my Roblox account using my phone and input into the username prompt: my Xbox gamertag username and my Microsoft password as my Roblox password and it didn’t work. During this I had not unlink my Roblox account from my Xbox account. Also when you stated to go to link social accounts in the Xbox account settings I didn’t see anything related to Roblox at all. I don’t know what to do. I’m sorry that I may not understand what you’re saying and I appreciate your help in this situation

Hmm in that case I'm afraid you would need your Roblox unique username.

I would also try and contact Roblox support Nathan

Hi there! This is Ronnie, an independent advisor.

Nice to meet you and I hope you are having a great day!

I understand you need help on your Roblox account.

Just a heads up that your Microsoft account is different from your Roblox account. So if you forgot your Roblox username or password, you can try checking some option on recovering them from the Roblox website.

If you are having problems recovering this, I would suggest to reach them directly so that you can get some options for recovery.

You might have used different username from your Roblox account and that is why you are having a hard time.
