Some friends and I have defeated a few other devices with face unlock features. It was the super technical task of finding and printing a photo found on social networking sites, then holding it up to the camera. I wonder if apple has hardened against this.

30 seconds of googling would've told you that it uses a 3D mapping camera + IR to scan your face.

So no, printing a photo found on social media won't work. 3D printing a perfect model of a face might, we'll see.

Unlikely, since they hardened their model against professional face masks.

but the market for professional face masks that can pass a faceid check just opened up.

They did mention in the keynote that they worked with photos, as well as professional maskmakers and makeup artists to prevent this

It uses a depth sensor. And they have trained the neural networks to prevent using 3d printed masks instead of the real face. I guess they are using depth-ir-powered-video instead of still photos.
