What Should Be Considered First?

Before we get into more in-depth solutions, it is likely that the problem is caused by the improper use of Face ID and therefore you should consider the following;

1. Make Sure Your Face Can Be Seen Correctly

The TrueDepth Camera on you device has to be able to recognize your face properly. Make sure that your entire face including your eyes, nose and mouth are visible to the camera. Do not wear sunglasses when attempting to set up Face ID and make sure you are in a well-lit room.

2. Make Sure Nothing is on the Camera

At the same time, you need to make sure that nothing is covering the camera. If the device has a screen protector or case, remove it before attempting to set up Face ID. You should also clean the camera to remove any dust or dirt that could be obscuring the camera.

3. Make Sure the iPhone Is no Further than Arm’s Length

The iPhone has to be close enough to your face to adequately capture your Face’s details for Face ID not working correctly. The device shouldn’t be further than arm’s length and also make sure that there is adequate light on your face.
