TouchID was removed because it took up space on the front of the phone and Apple wanted the screen to be bigger. There's no deeper reason than that.

> Will Apple continue progress and built in PinchID - a tiny needle that sting you to test if you are you based on your blood/DNA?

I struggle to believe you when you say that's a serious question...

> Im also concerned about the data Apple will collect.

The FaceID data will be stored in the secure enclave locally on your phone, just like TouchID data was. Apple will not collect it.

The Pixel handset has the fingerprint sensor on the back of the phone. It appears to work quite well. Much of this needless outrage could be obviated by allowing multiple simultaneous biometrics for auth; while taking the phone out of your pocket, place your finger on the sensor to initiate FaceID.

That's very un-Apple.

How would I use my phone on a desk without lifting it up? I can do that with TouchID, but if the sensor is on the back, I can’t.

I confess, never in my years of phone ownership have I had that specific use case, or considered that it might be important for others. Do you find yourself doing that often? If so, can I ask what for?

You can't really do that with the face id either, unless you loom over your desk in an awkward way.

From their promo video of iPhone X, FaceID works at angles over 45° (see the swimmer portion)

Second, facial features are more unique than fingerprints - according to apple's own presentation, there's a 1 in 10.000 chance that prints from different people would unlock it. With face ID, this becomes 1 in 50.000 (iirc).

I believe they said 1:50,000 and 1:1,000,000.

He's not correcting the use of a period, he's correcting the numbers themselves. 1:50,000 and 1:1,000,000 vs 1:10,000 and 1:50,000

Unless you have a twin.

Twins have different fingerprints.

TouchID is trivially defeated by a 6-year-old:

Did you read the article? Troy Hunt addressed that.

All the more reason for FaceID
