How do I sign into my xbox one account??

how do i sign out of my account from other xbox one?

hello, i understand there are problems with signing into child acounts on xbox live, i am not a child and would wish to change my account to an adult one , how do i do this?

I signed in on my Xbox and do you have a suggestion on how I can sign into my Microsoft account if I can't get into the email I used for the account

If you have important proof of ownership for that account (emails, important screenshots, etc)
You can try opening a chat with Microsoft support and explain them the situation

(Please note that this doesn’t guarantee an account recovery)

Hi, unfortunately no one at Microsoft can send password reset links or modify account information due to security reasons

If none of the methods above worked for you, you may need to create a new account :c
