Two flat images, one for each of the sensor's camera

  That’s not how they work. They emit structured light in the form of an array of infrared dots and they measure the time of flight to where the dots strike something. Maybe new ones are different but that’s how they used to be. Little Kinect devices, really, for sensing faces instead of whole people.

    You are exactly right. There's a description here: https://learn.microsoft.com/en-us/windows-hardware/design/device-experiences/windows-hello-face-authentication https://learn.microsoft.com/en-us/windows-hardware/design/de... These cameras are considered a "secure biometric" device and AFAIK nobody has faked them. I've flagged the poster who said "try two flat images"
