Windows PIN Is Not Available or Sign-In Options Are Missing
Restart your PC
Temporary Windows authentication issues can sometimes be resolved with a restart.
Use your password
Select Sign-in options on the Windows login screen and use your Microsoft account or local account password if available.
Reset your PIN
Navigate to:
Settings > Accounts > Sign-in options
Select PIN (Windows Hello) and choose the option to change or reset your PIN.
Verify your Microsoft account
Make sure your Microsoft account can successfully authenticate online.
Install Windows updates
Windows Hello issues can occasionally be corrected through cumulative Windows updates.
If you are unable to access the account at all, use Microsoft's official Windows account recovery options.
