At first reading this I thought "My iphone recognizes me right when I wake up so I'm sure someone could use unlock it while I was asleep or unconscious" but I tried it a few times while making a 'passed out' face and it turns out, nope. At least I couldn't get it to. Even tried using my hands to hold open my eyelids and it didn't unlock. That's pretty impressive.
- deergomoo 7y agoThere’s a setting “Require Attention for Face ID” that controls this. It’s enabled by default, but if you’re unable or find it difficult to look directly at the sensor (or wearing sunglasses that block IR) you can turn it off and make it behave like the Pixel. You can even point it at your face while looking away, and it won’t unlock until you make eye contact.

- rtkwe 7y agoThe iPhone uses the blaster IR + the camera to tell if you're looking at the phone to avoid this. Android should be able to implement this though because it really just looks for the IR reflecting off the back of your eyes which only happens when you're looking right at the light source. It's the same thing that causes(ed) red eye in photos.
