1Password 8 (Early Access) Issues list.

Hello oilburner, I'm sorry to hear about the issue with Biometric unlock.

There are a few device requirements in order to enable face unlock with 1Password. 1Password requires devices to use Google's native Biometric framework as well as use strong encryption. To clarify, many devices have a facial scanner, but may not support Google's native Biometric framework as well as support strong encryption. Part of that support includes requirements for a front facing camera that can capture facial biometry in three dimensions. Without it, there's a possibility a photograph could be used to trick the facial scanner. Currently, this support is limited to a small number of Android devices and I do not think it's available with Galaxy tablets.

If your device has a fingerprint scanner you can use that instead.
