If that isn't successful, players may want to unlink their connected accounts they have access to and link them to another Bungie profile. Bungie is not able to remove connected platform accounts from profiles under any circumstances.[/quote] You will need to work with [url=https://help.steampowered.com/en/]Steam Support[/url] in order to try and recover the account used. in order to deactivate Cross Save and unlink the account.
