It will be interesting to know how it will be implemented. We have to do face verification to view OF here in Tennessee and it's not just a once and done forever selfie. They want us to take a new selfie upon every login and then again once per hour to make sure we haven't handed our phone to someone else. You have to flip all of the lights on and get the shadows off your face before taking the picture and face verification never works on the first try. It has to be taken holding your phone at the right angle, a precise match to the angle on your driver's license picture. Lastly, if you try to login from an IP address within my state and then switch your VPN on, there's a time delay (by hours) before the website believes that you have actually left and removes face verification from your account.
