With just a glance, Face ID can unlock Apple's new iPhone X, giving owners a new authentication paradigm for the first time since the arrival of Touch ID with the iPhone 5. Face ID – that's Apple's name for the technology – uses a complex front-facing camera system and accompanying software to unlock the iPhone and authenticate purchases and payments with a mere glance.
The futuristic-seeming tech is one of the iPhone X's main selling points, along with its "Super Retina" OLED screen, slimmer, bezel-less form factor and improved camera. But it also raises questions about whether the technology is as easy and secure to use as the tried-and-true fingerprint-based Touch ID.
