Keep your eyes open

Keep your face turned toward the camera

Keep your face clear of obstructions such as stray hair or glasses that were not present during your initial face registration

Avoid making the following expressions:

Laughing

Raising your eyebrows

Closing your eyes

Looking away from the camera

Looking sideways

Frowning

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.
