Removing my account on xboxs.

Thank you for taking the time to post this on the Xbox Forums, Adam.

As stated by Xbox Forums Ambassador Mythic Sandman, there is no way for you to remove your account remotely from another console, only again,
prevent other from signing in by updating your password.

If you are unfamiliar of how to do this, you can see this by viewing the article that covers

How to change your Microsoft account password article.

As there is no further information that we can provide to you on this matter, we will now be locking this thread. If you have any other questions or concerns that differs from this matter, please, feel free to create a new thread and will cater to you there.

Thank you for being part of the Xbox Family, and we wish you a wonderful day.

Hello and of course you can remove your account remotely, the only thing you should do is enter your microsoft account from here you can, in the image of your profile on the upper right side, enter there and then you will find in the menu a section of
devices, enter there and it will only be a matter of selecting the xbox or device you want to withdraw your account

No but you can change your password making it impossible to login again on other consoles.

Try to remove and add back your profile on your console, then see how it goes from there.

Is there a chance that the hacker removed my order history or removed the xbox account from my microsoft account?
