If your wife's PIN is not working and she cannot remember her password, there are a few options you can try to regain access to the computer:
- Reset the PIN from the Lock Screen: If the PIN credential provider is selected on the lock screen, she can select the option "I forgot my PIN". This will prompt her to authenticate using an alternate method (like a password or security key) if available.
- Use an Alternate Sign-in Method: If she has previously set up an alternate sign-in method (like a Microsoft account), she can use that to sign in. After signing in, she can navigate to Settings > Accounts > Sign-in options and reset her PIN.
- Check Network Connectivity: If the device is a Microsoft Entra hybrid joined device, ensure that it has corporate network connectivity to the domain controllers, as this is necessary for certain PIN reset scenarios.
- Recovery Options: If the system is unresponsive when requesting a password reset code, you may need to check the internet connection or try resetting the device using recovery media if available.
If these options do not work, you may need to consider contacting Dell support or a professional technician for further assistance.
