TBD: Face ID is NOT as secure as TouchID!

[SinisterDuck]

I can tell you my twin brother picked up my phone the other day and successfully unlocked it every time he looked at it. Not that I’m worried about him looking at my phone

If I had a twin, I wouldn't be concerned at all. He would probably be the person I trust most, unless he was an evil twin and was looking to take over the world and needed my phone to do it. I might be concerned then.

According to your nick, you would be that evil twin in that scenario.

All jokes aside, while it seems to be possible for a twin to unlock the iPhone X, it’s not a guarantee that all identical twins will be able to do so.

I envision a future combo of Face+TouchID for a truly ironclad secure authentication
