Locked out of my surface pro

On the login screen > Click Sign-in options > Choose the PIN icon > Click “I forgot my PIN” >Sign in with your Microsoft account password

Create a new PIN

After that:

Go to Settings > Accounts >Sign-in options > Select Facial Recognition (Windows Hello) > Click Remove> Click Set up again

Use the PIN or password sign-in path first, then repair Windows Hello. If the PIN truly no longer works, reset it, then re-enroll facial recognition.

1. On the Surface sign-in screen, select Sign-in options and choose Password instead of Windows Hello Face or PIN. Sign in with the account password if possible.
2. Once signed in, make sure Windows and Surface firmware are fully updated:
   • Open the Surface app (or install it from Microsoft Store if needed).
   • Go to Help & support and select Check for updates to open Windows Update and install all available updates.
3. Reconfigure Windows Hello Face:
   • Go to Start > Settings > Accounts > Sign-in options.
   • Under Facial recognition (Windows Hello) or Windows Hello Face, choose Remove (if present), then Set up and follow the prompts.
   • If recognition is unreliable (for example, different lighting or with/without glasses), select Improve recognition on the same page and scan again.
4. If the PIN is not accepted but the password works:
   • Sign in with the password.
   • Go to Start > Settings > Accounts > Sign-in options > PIN (Windows Hello) and select I forgot my PIN to reset it.
5. If neither PIN nor password lets you in, but the device previously worked and recently changed (for example, after an app/driver/update):
   • Use the password if at all possible and then consider a Restore or reset of the PC only as a last resort, because this can cause data loss. See Restore or reset Surface for Windows from the troubleshooting article before proceeding.

The Surface not appearing under devices in the Microsoft account does not affect local sign-in with PIN or Windows Hello. Focus on signing in with the password, then repair or reset Windows Hello and the PIN from within Windows.
