Because I have windows, it autofilled my microsoft windows account into the "Link an Xbox Account" field for cross save. This isn't my xbox account and it doesn't even have destiny. I can't seem to find the option to remove that account and put in my actual before committing to cross save. Please Help!
Hey there! You will need to disable the autofill for your browser. If you want to unlink the account, go to Settings > Accounts and Linking to unlink the account. You must be able to authenticate it in order to unlink it. If you do not know the credentials to the account, you will want to contact Xbox to help gain access to that account.
