Has anybody ever thought about how Face ID is pretty much a backdoor into your iPhone? Think back a few years to when Apple refused to open a felon's iPhone for the US government, because "they couldn't." If that happened now, they wouldn't even have to ask Apple, given the felon has Face ID enabled.
Edit: I'm kind of surprised by the downvotes, given I thought HN was pretty big on personal privacy. Just thought I'd stir up the discussion, that's all.
Edit 2: I personally think U2F is the way forward here, not Face ID or Touch ID or other biometrics.
The main alternative to biometric ID is a PIN. Those are seldomly changed, and are relatively easily shoulder-surfed. I've seen children who can't even read yet learn their parent's iPad PINs. If you're afraid of the police, surveillance needs to be your threat model.
Just as an FYI for anyone reading this thread: Android has a similar feature called "lockdown", that can be triggered by holding down the power button for a second and then selecting the option.
There's limitations. iOS requires a passcode after so long and after so many bad attempts or after a reboot. The time law enforcement would have to use your face to get in is pretty short.
