To remove two-factor authentication from your Rockstar Games Launcher account, you will need to delete the sign-in methods associated with your Microsoft account. Since you cannot access the Microsoft Authenticator app on your lost phone, you can follow these steps:
- Go to the Microsoft security info page: https://aka.ms/mysecurityinfo.
- Sign in with your Microsoft account credentials.
- Review your sign-in methods and delete the authenticator app method.
- After deleting the authenticator method, you should be able to receive confirmation emails at your registered email address instead.
If you encounter any issues, you may need to contact Rockstar Games support for further assistance with your account recovery.
