    Hello Still_Active,

     

    Try these steps:

     

    1. Open Registry Editor.

    2. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\PasswordLess\Device.

    3. Set DevicePasswordLessBuildVersion to 0.

     

    Note: It is recommended to create System Restore point before editing registry.

     

    Reboot and check if you can sign in with Microsoft account password now.

     

    Hope this helps!
