Craig Federighi answers an email, gives us some deets on FaceID

Keith Krimbel sent an email to Craig Federighi, asking three questions:

  • I’ve seen the explanation for what happened on stage at the keynote. Will this happen every time someone else interacts with my phone when it’s locked? I’m concerned the phone will require a passcode much more often than TouchID does.

  • Will FaceID work with sunglasses?

  • What will prevent a thief from taking my phone, pointing it at my face, and running?

Great questions. And Craig took the time to answer them, as seen in the tweet below. Thanks for asking Keith, and thanks for sharing.
