Ive accidentally logged out of my account on my Xbox One S that ive had for 7 years now. I know the email that my account is linked to but that email and the phone number linked to the account are my mums old ones she doesnt have access to anymore,we also dont know the password. I have a xbox series s that is logged in to the same account and i also pay for xbox live gold. Is there any way i could log back in or get my account back?? Ive tried going through every microsoft login form i could find but none of them helped
