Are you ready to unlock your iPhone with your face?

Your passcode can be hacked, but your face is yours and yours alone. That's the thinking behind Apple's latest security measure, which is more high-tech and a bit more intimate than anything else on the market. With Face ID, which Apple unveiled Tuesday, owners of the company's new top-of-the-line iPhone X will be able to unlock their phone, pay for products and use mobile apps just by glancing at their device. "Nothing has ever been simpler, more natural and effortless," Phil Schiller, senior vice president of worldwide marketing, said during Apple's first product launch at its new headquarters in Cupertino, Calif. "Face ID is the future of how we unlock our smartphones and protect our sensitive information."
