How Secure Is the iPhone X's FaceID? Here's What We Know

In its quest for hardware perfection, Apple can't seem to resist testing the balance between making things easy and making them secure. Sure, a six-digit passcode is virtually impossible for a thief to crack before his repeated attempts lock the phone, but it demands an unacceptable fraction of a second for you to tap it out. Even TouchID requires a home button that Apple has deemed unsightly. Now, in its continuing war on inconvenience, Apple has replaced TouchID in its new flagship iPhone X with FaceID, a system where your face acts as password. In doing so, it's about to give an unproven biometric security technology its biggest field test yet.
