How can i see what account i linked to my apex?

@yaab1221 If you have any of the games on this list you can use that to find the linked account: https://help.ea.com/en/help/account/find-your-ea-account-email-address-using-your-game/

Usually you'll share the email address between your console account and the ea account. 

If you're struggling to find the right account, you can log into Origin, then go to the profile page, then Edit on EA.com. On this next page you should be able to see any linked accounts.
