Try these steps in order:
- On the sign-in screen, look for Sign-in options.
- If available, switch from PIN to Password and sign in with the account password.
- If the device uses a Microsoft account, use that Microsoft account password.
- If the sign-in screen shows I forgot my password or I forgot my PIN, use that link directly from the sign-in screen.
- For PIN problems, reset the PIN.
- For password problems, reset the password.
- If the PIN setup keeps reappearing after updates or security changes, try creating the PIN again.
- Windows Hello PIN issues can happen after security updates or system changes.
- If PIN creation fails, sign out and sign back in, then try creating the PIN again.
- Restart the device again, but if updates are pending, use Update and restart.
- This can clear temporary sign-in issues and complete any pending update state.
- After signing in successfully, go to Settings > Accounts > Sign-in options to manage or recreate the PIN.
- Keyboard path: press Windows logo key + I > Accounts > Sign-in options.
If the loop continues and password sign-in is not available, use the Windows sign-in recovery articles for the exact sign-in method that is failing:
- Forgot your PIN
- Change or reset your Windows password
- Forgot your Microsoft account password
