Hi @Jackfff-07,
You can find instructions on how to link and unlink accounts here: Unlink your platform accounts from your EA Account & Linking your platform accounts to your EA Account.
Please note that, when you link accounts, it creates a lifetime link to protect you from malicious activity and help prevent performance issues in your games.
You can unlink your platform accounts from your EA Account if you want to link them to a different EA Account, as long as that EA Account has never had the same account type linked to it before in its lifetime.
That means if you unlink an Xbox gamertag from your EA Account, you can’t link a different Xbox gamertag to it in the future.
Unlinking risks for Apex players
If you unlink a platform account that you use to play Apex Legends, you might have issues with Battle Pass leveling, item unlocks, and other errors.
Instead of unlinking and relinking a platform account you play Apex on, we recommend starting fresh on a new account.
