What is Face ID?

Face ID is the face scanner on your iPhone or iPad. Does the scanner recognize your face? Then your device unlocks. Face ID is a simple and secure way to unlock. This is important because you want to protect your digital life on your iPhone or iPad. After all, we store our entire life on these devices. I will tell you more about how Face ID works and how safe it is.

What is Face ID?

Set Face ID

With Face ID, my face is now my password. How it works? The infrared lamp recognizes my face when I look at my device. The infrared camera makes a scan of my face. The grid project maps my face with around 30,000 dots. All these images are cleverly bundled to make a model of it. That model is compared with the model that I have pre-set. Do both models match? Then my iPhone unlocks. Easy right?

When does Face ID work?

You even recognize Face ID when you partially cover your face. Even when you wear sunglasses, scarf or hat. Your eyes, nose and mouth must always be visible. You do not have to hold the device in front of your face. Are you looking at your iPhone while it is on the table? Chances are your iPhone will unlock. It works from every natural position and even in the dark. Face ID also gets to know users. Are you suddenly growing a beard? No problem. Aging also does not play a role.

When does Face ID not work?

Unlock with Face ID

So Face ID gets to know you. With major outward changes such as shaving off a very full beard, Face ID has some more difficulty. Face ID then asks you for your access code. After entering your access code, your face data will be updated immediately based on your new appearance. Sometimes Face ID does not work at all. For example if you cover too large a part of your face, such as a mouth cap. In addition, Face ID only works if you look directly into the camera. So it doesn't work with your eyes closed.

How safe is Face ID?
