Krimbel also asked for details on what would prevent a thief from taking the iPhone X, pointing it at his face, and running off. In response, Federighi says there are two mitigations in place. "If you don't stare at the phone, it won't unlock," he wrote. "Also, if you grip the buttons on both sides of the phone when [you] hand it over, it will temporarily disable Face ID."
