Windows hello face used to work now it doesn't

Hi! My name is Aj and Im an Independent Advisor here to help!

This usually happens after update, driver issue or a change in camera settings. Kindly try to go to Settings > Accounts > Sign-in options > Windows Hello Face and see if it shows any error. Make sure the IR camera driver is up to date: Device Manager > Cameras > Right click > Update driver.

If that does not help, remove your face data and set it up again.

I highly recommend to update IR based webcam driver.

If that doesn't helps, try removing Windows Hello PIN, and re-setup it followed by re-setup of Windows Hello Face.

If issue still persists. refer other suggestions in this fix:

Hello Douglas McCaustland,

Thank you for reaching out to Microsoft Q&A and informed the issues. Based on your description I believed that the biometric verification is not working after an update, here's how to tackle this issue:

1. Reset the Database:

• Open Run Dialogue (Windows + X) > Then input services.msc > Enter > Navigate to Windows Biometric Service > Right click > Stop

2. Delete the Database file:

• Go to This PC and open Local Disk (C:) > Windows > Systems32 > WinBioDatabase > Delete all the file inside the folder

3. Restart the database:

• Open Run Dialogue again and input services.msc > Enter > Windows Biometric Service > Right click > Start
• Restart your PC

4. Clear TPM (Last Resort):

(Disclaimer: This will erase all your keys, passwords stored in TPM which can affect other security feature, be sure to backup all of your keys and passwords before proceeds)

• Open Run dialogue > input tpm.msc > Enter
• Click Clear TPM on the right panel and follow the on-screen instruction and your PC will restart
• After Restart you can go to Sign-in options in Windows settings to reconfigure your PIN
• Once PIN is set you can setup your Windows Hello Face again
