Is it possible to sign out of a Xbox you no longer have physical access to

Hello, first it's a pleasure to be able to help you today.

My name is Welcome to the community.

Hello Andrew1007543, unfortunately it is not possible to do a remote logoff, you can however change your password and remove payment methods from your account.

I’m sorry to say, but both of the previous responses are totally incorrect. There is no way to remotely sign out or remove your profile from a console you don’t have physical access to. That said, if you want to prevent your profile from being used on a
console you no longer have access to, all you need to do is change the password of the Microsoft Account that is associated with your Gamertag. More info at the links below :

There is no way to remotely remove your account from someone's console. You would have to physically delete it yourself. Removing their console as your Home only means they can no longer access your games from their own account. If your account is still
sign in on the console, they can still access it.

No,it's not possible for anyone to hack your xbox console unless they have physical access to it. It can't be hacked online.

hmm ok what if they hacked my router is it still not possible?

and by physical access to it, should they have been in to my home to do it? or premanent physical access to it?
