Image change: Although we have already dealt with some particular situations
like varying hairstyles or facial hair, some significant changes, such as shaving
off a beard, can affect the accuracy of the face image verification. To avoid
failed verification, register a new face image. For more information, see Register
face image.
Light: Ensure you are in an environment with steady and even light. The
following situation may affect the results:
Bright light behind your head
A window with bright light
Bright light pointed directly at your face or the camera
Insufficient, directional light, such as a reading lamp
Darkness
Glasses: Because different glasses have different effects on light, we recommend
you to take off your glass or wear untinted glasses with very narrow rims. Be
sure to take off dark colored glasses like sunglasses or sports glasses.
Video camera: Be sure to use the same video camera when you log in or out.
Images taken by different video cameras might produce different effects, which
can cause the face verification to fail.
