Select three responses.

Face ID is a biometric authentication method that allows you to securely unlock your iPhone or iPad, authenticate purchases, sign in to apps, and more, all with just a glance. However, there are situations where Face ID is not permitted and you need to enter your passcode instead.  According to the Apple Device Support Reference Materials 1 , these situations include:

The device has just been turned on or restarted.

The user hasn’t used their passcode or password to unlock their device for 156 hours (six and a half days), and the user hasn’t used a biometric to unlock their device in 4 hours.

The device hasn’t been unlocked for more than 48 hours.

Therefore, the correct answer is C, D, and E.
