Face ID is Apple’s next big thing, in terms of security, and it’s one of the benchmark features for the upcoming flagship iPhone X.
A couple of curious potential iPhone X customers reached out to Apple executive Craig Federighi via email, asking a couple of questions regarding Face ID, how it might work with sunglasses, and whether or not it can be disabled quickly in some specific situations. According to Federighi, Face ID will work with “most” sunglasses, and, in the case of a thief holding up your phone to your face, there are a couple of ways this would result in a stolen, unlocked phone.
First, with sunglasses, Federighi says that “with most, but not all” sunglasses let in enough IR light that Face ID will be able to recognize the user’s eyes. He adds that it’s “really amazing!”.
When asked what would prevent a thief from taking the iPhone X, holding it up to the owner’s face to unlock it, and then running away with the unlocked phone, Federighi said this:
“There are two mitigations: if you don’t stare at the phone, it won’t unlock. Also, if you grip the buttons on both sides of the phone when you[r] hand it over, it will temporarily disable Face ID.”
Just for fun, Federighi also notes that the situation he ran into on stage at this year’s September event, where Face ID appeared to fail, was due to other people using the phone before he got his hands on it, and face in front of it. He says that for a phone that one person has been using for months, Face ID failing “has never been a real problem.”
