I suppose you could try to set it up with your eye blinked and then try it with eyes open and see how it works... but I doubt it will stop it, as the algorithm is simply a probability at the end of the day based no the inputs, its designed so that you can still open it if you have sunglasses on, or a hat, or you shave or grow a beard, so the wiggle room in the algorithm probably isn’t going to fail just because you wink or don’t wink.
It is good tech, identical twins generally cannot open each others phones with it.. but I just don’t like the whole concept of it... and like this story proves, you have no expectation of privacy to your face.
Me either! And I was looking forward to being able to say goodbye to passwords and pass phrases. But I guess that'll have to wait for quantum iPhones.
