Hi there, Thanks for reaching out. Swfan77 and Xaren below are correct in saying that Bungie is unable to update links to Bungie.net profiles on behalf of players, as you will need to log in to any accounts to prove ownership. To confirm, this Steam account currently linked to this Bungie.net profile is not yours and was added without your authorization? If so, prior to this account being added to your Bungie.net profile what other platform accounts did you have linked (Xbox, PS4, Battle.net, etc.)? Looking at your account it does not appear that Cross Save was ever enabled or disabled, as well as any other platform accounts linked. This means that you can easily create a new Bungie.net profile and connect your platform accounts to it instead, abandoning your previous Bungie.net profile. This will however result in any special code redemption emblems being lost as they are tied to your Bungie.net profile and not your game accounts. We notice you commented below about being unable to migrate your Battle.net account to Steam due to it being already set for migration. Please keep in mind that PC Migration is a one time process that cannot be changed or undone.
