Facial recognition

Hello Bill,

We need to do further investigation on your concern so that we will know why the facial recognition quit working:

• Have you recently made any changes/updates prior to this issue?
• Is there an error message when you try to sign using facial recognition?
• What is the make and model of your computer?

In the meantime, I would suggest that you perform the troubleshooting steps in this
article.

We will wait for your response.

Regards.

Facial recognition and pin not working for login

I have NO idea where to put this one, and I can't find anything online.

Dell Precision 7740. 5 months old. Dell has replaced the motherboard twice, second time MB and memory. It's working today, but the facial recognition and pin don't work. They haven't worked since the first MB replacement.

The technician that replaced the MB told me it wouldn't work 'til it was re-set up.

Login using password. Go to Accounts>Sign in options. It SAYS my pin is there. I have removed it and recreated it.
Open Windows Hello face and hit set up. Opens and says "Get Started". Hit that. It pops up and requires my PIN. I enter it, it flashes and disappears...

At LOGIN, in the sign-in options is the Pin. When I select the Pin I get:
Your PIN is no longer available due to a change to the security settings on this device. You can set up your PIN again by going to Settings > Accounts > Sign-in Options...

I've BEEN in the *&^%$#@ sign-in options over and over. It SAID my pin was set. I changed it. I rebooted. I still can't log in with the pin. I tried again to set the facial recognition. It has me enter the pin then closes.

What does changing the motherboard have to do with using a pin or facial recognition in the first place? And WHAT do I have to do to get this thing to accept the pin and use the Windows hello face?
