How do I unlink an EA account from Xbox without having access to the EA account anymore?

You should be able to unlink your Xbox account from your EA account by signing into your EA Account and under your profile info you should see all the linked profiles.

I can't get into my EA account anymore though. So is there a way I can do this from my Xbox account?

If your account is linked to an EA account that you do not have access to, you will need to talk to EA to unlink the account. No linking or unlinking process is done on the Xbox side.

Hi Yeenoiz. My name is Kyle and I'm an independent advisor.

The account connection is created on EA's side, therefore it can only be unlinked from EA's side.

When signing in to the EA website, choose to login with your Xbox profile. This should allow you to access the linked EA account.

If you can get into the account, follow the steps on EA's help page to unlink the account: https://help.ea.com/help/account/unlink-gaming-accounts-from-ea-account/

For further help with recovering access to the account and unlinking it from your Xbox profile, please contact EA. You can find more info on how to set up a case with EA at the EA Help website: https://help.ea.com/help/faq/contact-ea-help/

Thanks,
