Replied on February 8, 2021 If you have the account information that was shown in the Roblox game, you should be able to log into that account on PC. If this does not work for you, they will have more information on the Roblox website.
To connect your Roblox account to your Xbox account, you will need to know your correct user name and password. If you have forgotten your password and need to change it, click here for information on how to reset your password.
To vary the default setting to your little one:
Connect to Xbox-enabled devices. You’ll need an account to play games and access other experiences on your Xbox console, Windows PC, and Xbox mobile apps. If you don’t already have an account, you can create one for free.
To connect your PC to your Xbox One console: On your PC, open the Xbox Console Companion app and choose the Connection icon on the left side (looks like a little Xbox One). Choose your Xbox, and then choose Connect. From now on, the Xbox app will connect to your Xbox One automatically, as long as it's on.
Playing Experiences on Xbox You can play all of the available experiences on Roblox cross-platform with your friends even while they're playing on PC, Mac, or a mobile device.
The games on Roblox are also completely cross-platform, meaning you can create an account and all of your data will be saved for when you play on mobile, Xbox, PC or even VR. When it comes to playing these games, you will need a Roblox account, and luckily, they are quite easy to create.
As of right now, you cannot play Roblox on PS5 or PS4. Roblox is currently not available to purchase or download on Sony's PlayStation consoles. You can technically try to play it via the PS4's web browser, but this is not a good way to play the game.
Click the golden hexagon in the top right corner, next to the settings button, and select the amount of Robux you want. (Keep in mind that the only options currently available on the app from the Microsoft Store are 80 Robux, 800 Robux, or a premium subscription with 450 Robux per month).
After you launch the Roblox experience on Xbox One you'll see two buttons. One is to play as your Gamertag and the other is to Sign In as your Roblox account. Select Sign In and enter your Roblox account info on the next screen.
At the bottom of your Profile, go to the “Account Links” section, and click on Consolidate Accounts. As you scroll through your Sub-Accounts, you will find a “Merge Option” drop down menu that corresponds to each user.
On your logged-in device, go to Account Settings then Quick Login. After heeding the warnings, enter the one-time code shown on your new device, and click Enter. Review all details before selecting Grant Full Account Access. A success message will appear once your new device has logged in.
