Quick Scoop: In Opera GX, the Roblox account linked to GX Rewards usually can’t be changed after it’s been registered. Community reports and Opera GX discussions say the link is effectively permanent once you authorize one Roblox account on that browser/device.

What you can do

  • If you only want to play Roblox, use Roblox’s built-in Account Switching in the web version: click the gear icon in the top-right of Roblox Home and choose Switch Account.
  • If you need a different account for GX Rewards specifically, the common workaround people mention is using a different browser or device, since the Opera GX reward link appears to stick to the original account.
  • Log out of Roblox and sign into the other account if your goal is just to change which Roblox profile you use in the browser, not the GX Rewards binding.

Important limitation

Roblox’s account switcher works on the web and is intended for users 13+ without parent privileges, but it is separate from Opera GX’s reward/account binding. That’s why switching inside Roblox may not remove or replace the account Opera GX already tied to GX Rewards.

Practical steps

  1. Open Roblox in Opera GX.
  2. If you only need a different login, use Roblox’s Switch Account option from the gear menu.
  1. If the issue is GX Rewards, try opening the reward page in another browser or device and authorize the correct Roblox account there, since Opera GX reports suggest the original binding cannot be edited.

Note

The most reliable answer from current reports is that you can switch Roblox accounts in Roblox, but you usually cannot change the Roblox account already attached to Opera GX GX Rewards.
