Earlier quoted context omitted.

Twins and siblings that look like you are not random people.

Now I'm imagining the FBI using its facial-recognition databases and tracking down people who look like the phone owner to wave an iPhone in front of their face.

I'd watch that TV show.

"Dylan and Luke are bounty-hunters of a new breed. They have to find the long-lost twins of suspects on FBI's Most Wanted list. On this episode of Face Hunters..."

Biometrics are UID's - not passcodes.

If a user ID is sufficiently long, there’s no practical difference between that and a passcode (it becomes a “login key” which both uniquely identifies the user and acts as a secret). If everyone in the world had a secret 128 bit user ID, we wouldn’t need passcodes. Having the iPhone X scan a device-specific, random pattern of the user’s face is somewhat close to that.

I'm genuinely interested in knowing how apple can tell that FaceID is better than TouchID - TouchID is already very fast - I can give access to someone else with TouchID without giving my password - It's unlikely that someone will be able to unlock my phone without me knowing it when using TouchID - In case of coercion, I still have the possibility to give the wrong fingerprint 9 times before the good one - I have to…

> It's unlikely that someone will be able to unlock my phone without me knowing it when using TouchID Do you really think it's likely that someone will steal your phone and then trick you into looking at your own phone without you realizing it? At that point you might as well be tricked into putting your finger on a TouchID sensor.

I wonder...would it be possible to 3D print someone's likeness so as to spoof the FaceID?

I highly doubt it’s easier to add FaceID than TouchID to any phone.

Biometrics are UID's - not passcodes.

Literally the second paragraph > Face ID doesn’t replace your passcode, but provides easy access to iPhone X within thoughtful boundaries and time constraints. This is important because a strong passcode forms the foundation of your iOS device’s cryptographic protection.

Also, “ID” is literally in the name.

Earlier quoted context omitted.

They said in the keynote the chance a random person could unlock your phone with FaceID is 1 in a million.

Can someone help me understand why @gre got down-votes here? I don't get it. As far as I remember, in the big reveal, they did make a point of saying that faceid had a much lower chance of of colliding than the fingerprintid system.

I'm not the down-voters, but my guess is due to citing the 1-in-a-million figure, which is Apple's claim about a random false positive, in response to a question about false positives with twins. Someone reading fast or simply not thinking critically could come away with the wrong impression.

You would also have to make the 3D print mimic the same infrared emission patterns as the original person’s.

Well it's definitely possible to have me looking my phone held by someone else. And it's then too late...

I remember reading some articles about the difficulty to have a fingerprint sensor under a screen, it might well have been easier to have FaceID (easier does not mean easy)
