It requires attention to unlock. You can't force someone to stare at the camera just by force.
For example, you can unlock your girlfriends iPhone7
[doublepost=1511444360][/doublepost]There is more: you can unlock your GF's iPhone 7 while she is asleep, but you can't do that with iPhone X
That's pretty silly.
Hope none of us has to deal with that type of situation but you think someone can make you put your finger on the touch sensor but they cannot make you look towards your iphone to unlock it?
And most people turn the require attention feature off for the iphone anyway.
