PIN sign-in is a convenient way to log in to your computer through a four-digit code that is easy to remember, and use as the primary sign-in option on your Windows computer.

However, there are times when Windows 10 won’t let you add a PIN, or it is just not working anymore, as this user reports:

For the past few days, the login with PIN on Windows 10 Pro is not available anymore on my laptop.  On the sign-in options screen I can only add a PIN but not remove or change it. When try to add a PIN after Password confirmation it asks to confirm my identity with a PIN and then nothing happens anymore.  […] If I instead enter a PIN select forget PIN it only open the dialog to go to sign-in option screen to reset my PIN.  

Similar situations include:

  • The inability to add or update your PIN
  • Adding a PIN but not being offered the sign in option in the login screen
  • PIN sign in option is offered but the system rejects your PIN
  • PIN sign in is stuck and you need to reboot or use a different login option
  • The PIN was added but after an update, it is broken
