Have you or anybody else tried to crack it? Ease of use isn't the only part of good security. Would a picture work? A recorded video on an iPad? etc.

Windows Hello uses an IR emitter and camera to get a 3D map to verify in addition to the ordinary webcam, and I've confirmed that mine doesn't fall prey to the most obvious of exploits.

Of course, it makes the assumption that "<user>'s face in front of the computer means <user> wants to log in", which may not always be the case.

That being said, I'm eagerly looking forward to reading about its pitfalls once people crack it.

I wonder if your face would look different enough in the 3D map while under duress to stop it from authenticating. Or what about if you're unconscious? It sounds like it would be real easy to break this security with a $5 wrench.

That's the case for a lot of security, though?

I've read it is very accurate: even twins who look very much alike won't fool it.

But it still has some funny characteristics: if you train it for two people/faces (you can scan multiple times), it will happily let both people log into the account.

Another gotcha: if I go for a coffee I usually lock my PC (Windows-L). If I then go too slowly, it will recognize me again and log me back in, leaving the pc unlocked.

My wife has a Surface Pro 3, and slams it from standing on it's leg down on the keyboard cover. I wince every time she does this, because I expect the glass to shatter. But she never has issues with it sleeping.

It's like the technological version of "Go the fuck to sleep" I suppose.
