It keeps signing me out immediately as soon as I sign in.

Hey there, looks like the service is currently having some issues. You can check here

Hi! sorry to hear you're suddenly being signed out. It's incredibly frustrating, trust me I know! This issue is actually caused by an issue with your account usually and not the Xbox itself. Try this..

1. Remove just your profile from the Xbox
2. hold the power button on the Xbox for 10 seconds shutting down, then unplug it
3. Sign into your Microsoft account
   here Use the same email and password that you use for the Xbox
4. click on the security link then click update (enter your password again if it asks)
5. On the security info page make sure you have at least 2 backup email or phone numbers and that they are current
6. Make any changes if needed or if everything looks good go back to the main page of the account
7. (optional) If it has been a while since you updated your password, change it now
8. sign out and plug the Xbox back in
9. add your profile back to the Xbox and sign in

The issue should be fixed after that

Hope this fixes the issue for you!

The process of removing my account and then re-adding it worked for me. I was having the same issue.

Awesome, Glad to hear it!

I have the same issue. Just started. I sign in and then it immediately signs out. Sign in and immediately signs out.
