Will iPhone X Face ID Work in the Dark

Just like touch ID, no matter no light, or low light, you face remains scannable to iPhone X Face ID, with a flood illuminator. Then the dot projector capture you with 30,000 points for identification purposes.

Can iPhone X Face ID Work through Scarves, Beards, Glasses, Sunglasses

When you set up iPhone X Face ID, iPhone X will just memorize the face with the dressing up then. Does it still recognize you when you change, such as scarves, beards, glasses, etc?

iPhone X Face ID uses the Neural Network block in Apple's A11 Bionic system-on-a-chip, it continually learns and adapts to how your face, facial hair, hairstyle, and facial coverings vary over time.

With the dot projector making up to 30,000 points available, there's a lot of data for Face ID to work with. Apple also built and tested the system to make sure it works under the widest varieties of conditions possible.

Does iPhone X Face ID Work with Touch ID Apps

We know that all of apps at App Store are allowed to download with touch ID. So on iPhone X, without touch ID, can we still access to the apps?

Yes, touch ID apps will also work with Face ID. Apple has abstracted away the implementation details and simply lets the app ask for biometric authentication. If the ID matches, the app will be authorized.

App developers can also require Face ID for a second factor in secure apps, and generate and use ECC keys inside the Secure Enclave that can be unlocked by Face ID.

How Animoji Works with iPhone X Face ID

Animoji is another amazing feature to bring fun to users. But how does the Animoji work? Apple has a separate system, built into ARKit. It provides basic face tracking for Animoji. All it does is provide rudimentary mesh and depth data, though. It never touches Face ID data or the Face ID process.
