Greetings! Unfortunately, there is no way to remove accounts from your Cross Save setup if you cannot authenticate them when doing the deactivating process. This means any accounts you cannot access are stuck on your profile. If you haven't already, you could work with [url=https://help.steampowered.com/]Steam Support[/url] to see if they can give you access back into your account. If not, then the account cannot be unlinked from Cross Save as mentioned in the block below. [quote]Destiny Player Support and Bungie cannot modify or remove accounts linked to Bungie.net profiles. To protect player privacy and data, you must be able to log in to any linked accounts to prove ownership prior to modifying your linked account. If you no longer have access to a linked account, you will need to reach out to the specific platform’s support for assistance with account recovery options.[/quote] via the [url=https://help.bungie.net/hc/en-us/articles/360049498031-Destiny-2-Cross-Save-Guide#authentication-issues-0-5]Cross Save Guide[/url].
