This policy setting allows you to control whether a domain user can sign in using a PIN. If you enable this policy setting, a domain user can set up and sign in with a PIN. If you disable or don't configure this policy setting, a domain user can't set up and use a PIN. Note that the user's domain password will be cached in the system vault when using this feature. Fix: (1) GPO: Computer Configuration\Administrative Templates\System\Logon!Turn on PIN sign-in (2) REG: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\System!AllowDomainPINLogon
