xbox 360 profile sign in

Hello Beheld,

Thank you for posting here on the Xbox forums. We understand you would like to learn how to sign out of a profile from the Xbox 360. Is this correct? Are you currently using your own account? Is your friend's profile automatically being signed in to when
you start the console up?

You can either turn off the auto sign-in feature in the profile settings or delete the profile from the console entirely. Let us know if this helps!

How to add or remove an Xbox profile on Xbox 360

On Xbox 360, you can have your profile stored on a flash drive and sign in that way. On both Xbox 360 and Xbox One, you can require a pass code to sign into a profile as well. Essentially, they would have to sign in with their MSA and password, and then
enter the Pass Code to verify they are the owner of the profile.

To play games, even on Xbox 360, it has been required that you're signed into an Xbox Live profile (aka Microsoft Account). It's possible that previously it was configured to automatically sign in, and you didn't realize. It's possible that the account
that had auto-signed in removed the device from their account or changed security settings, and would require reauthorization to sign in.

Now, that is speculation on what might have happened as to why you're seeing a sign in screen unexpectedly. But the point would be that previously when using the 360, there was an account/profile being used.

This page here has details on how to add a profile to your Xbox 360. That would be for if there isn't
one present. Do you see if there is a profile already on there?

Signing in on Xbox 360 would actually not affect your Xbox One sign-in. You can use the same profile on Xbox One and Xbox 360 at the same time without conflict.

It does sound like your profile is being signed in elsewhere and that's forcing a sign-out, so a password change would be a good precautionary measure.

If you're signing into a 360, you'll need to download the profile to the console - https://support.xbox.com/en-US/my-account/manage-gamertag-and-profile/add-remove-profile-xbox-360
