Hi there, Thanks for reaching out. Regarding the specific Steam account in question, it's linked to your Cross Save setup, and has been since 2022. This means it was successfully authenticated when it was added to Cross Save. Further, the account name is somewhat similar to the name on your linked Epic account, suggesting it belongs to the same person. If the Epic account is yours, then the Steam account should be yours as well. If you still believe the accounts belong to a third party, though, we recommend consulting our [url=https://help.bungie.net/hc/en-us/articles/360048721292-Account-Security-Guide]Account Security Guide[/url] for advice. However, Bungie entrusts players with the security of their accounts and login information. In that case, you would need to reach out to Epic and/or Xbox support teams for assistance with the platform accounts. In any case, since March 25th's [url=https://help.bungie.net/hc/en-us/articles/35597981889300-Notice-Bungie-net-Account-Unlinking-Update-on-March-25-2025]unlinking update[/url], only Twitch accounts are now eligible to be unlinked from Bungie profiles. All other platform accounts, once linked, are linked permanently. Further, as Bungie entrusts players with the security and management regarding linking their accounts, we do not unlink any accounts on players' behalf. Thus, the Steam account in question will remain linked.
