Top 5: Things to know about Apple's Face ID

The iPhone X's Face ID feature has been getting a lot of attention lately, and it's raised a lot of questions. Here are five things you should know about it.

Apple's facial recognition system for iPhone X is not the first, but it is getting a lot of attention because it replaces fingerprint authentication entirely on the phone.

Should you trust that?

Here five things to know about Apple's Face ID:

1. Your face stays on the phone.

Or rather, the mathematical representation of your face scan stays in the Secure Enclave. Apps and the OS itself just get a yes or no on the match, nothing else is shared.

2. The face updates over time.

If you grow a massive beard between logins you may have to enter your passcode, but the system will then update to take account of the changes.

3. Masks supposedly can't fool it.

The system works when your eyes are open and looking at the device. Apple claims it worked with Hollywood experts in special effects to make sure a really good mask wouldn't unlock phones. It uses a second neural network to spot attempts at spoofing.

4. You're being scanned by infrared.

The TrueDepth system that's part of FaceID uses infrared so you can even unlock the phone in dark rooms. Apple says this is safe to use under normal conditions.

5. No matter what you look like, Apple says Face ID should work.

The company has claimed it trained the system on billions of images and claims it used a representative group of people. That means Face ID should work the same no matter your gender, age, or ethnicity.

You now know a little more to help you decide if you want to rely on Face ID in your phone.

Or at least you know enough to know it should still unlock even when your face still shows the shocked look at how much you spent on the iPhone X.
