How to sign an account of everywhere(Xbox,xbox app,etc.)

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

My name is welcome to the community.

Hello Requix, this is really strange, because when we change the password and add the 2FA after a while the person will not be able to enter.

Click on the link below and log in with your account.

https://account.microsoft.com/security

Go to the security tab and then click "Sign-in activity"

And see the login activities that were done to your account, or attempts.

Buddy, could you try uninstalling the game.
Then sign out from your Microsoft account on Xbox app and Microsoft store.
Sign in again everywhere and reinstall the game to see if the issue persist

are you signed into the windows store with that same account, as the xbox app is just a front and uses the microsoft store app for confirmation, downloading etc etc.

• Make sure you’re signed in only on this machine. If you have signed in to any other PC’s with the same account lately, ensure you’ve signed out everywhere else.
• Launch the Xbox App prior to launching the game, and ensure that your profile signs into Xbox Live without issue.

I have the same problem. My first Xbox experience is a bad one. Jumped through all the hoops to setup parent & child windows live accounts, entered card details etc. and it simply "doesn't work". My account shows as gold everywhere. Have signed in/out etc
still no joy. What a most basic fail.
