In that case, how many wouldn't be able to unlock a touch id device with 1:50 000 ratio?
Exactly. I would not hand it off to a sibling until a week has passed. The whole point of it is to learn over time. Unlike a fingerprint, it has to be able to handle many more nuances and yet be Abe to accurately get you. A better test would have been for him to use it for a week and then hand it off to his brother. What we also don't know from that video is did he give the passcode to his brother to unlock it when the faced failed. Not in that video, but we don't know elsewhere.
My guess is the first week is much more forgiving as it learns your face. I'd be really curious for those same brothers to have the owner use it for a week, without letting his brother use it, and then have his brother try a week later!
Here's a funny one from IFIXIT with the woman who did their X teardown:
With the iPhone X now in the hands of thousands of customers around the world, many early adopters are putting Face ID to the test to see if Apple's facial authentication system is as secure as it advertises.
Apple says the probability that a random person in the population could look at someone else's iPhone X and unlock it using Face ID is approximately 1 in 1,000,000, compared to 1 in 50,000 for Touch ID, but it notes the probability of a false match is different for twins and siblings who look like you.
We've already seen that Face ID can be fooled by identical twins, and now a video shared on Reddit appears to confirm that Face ID can sometimes fail to distinguish between siblings who aren't twins but have similar appearances.
In the video, the sibling who set up Face ID on his iPhone X was able to unlock the device with his face as expected. Next, he handed the iPhone to his brother. Face ID didn't authenticate his brother's face upon first attempt, but once he put on a pair of black rim glasses, his face was able to unlock the iPhone X.
Apple has been very transparent that Face ID can be less reliable in these situations, so the video doesn't come across as a PR disaster in the making for the company. But, it does visualize that Face ID isn't 100 percent failproof.
For those concerned about the security of their iPhone X in these cases, Apple's only recommendation is to use a traditional passcode instead of Face ID for authentication. Unfortunately, at least for the time being, that means disabling one of the key new features of a smartphone that costs at least $1,000.
Update: A similar video has surfaced of two half-brothers unlocking the same iPhone X with Face ID. The younger brother is supposedly 14 years old.
Not only do the siblings look somewhat similar, but Apple said probability of a false match is also different among children under the age of 13, because their distinct facial features may not have fully developed.

Here's a fun one from IFIXIT, featuring the woman who did the X tear down:
Your unlocking it wrong

Its either secure from the get go or not.

Except those 50,000:1 don't live in the same household. Touch ID for the win!
Apple's logic for the 1,000,000:1 is severely flawed. Those odds are DRAMATICALLY lower with siblings (obviously), and the fact those are much less secure than Touch ID within the same household.

Soooo... Face ID works until it fails spectacularly. Kinda. Maybe.
I guess not quite baked after all, despite the assurances that the tech was already in the basket last year. I'd wait until gen. 3 to see if it's going to replace everything else and only then consider a phone with it.

I used to play a baroque period flute, made of ebony - unlike most modern flutes made of metal. The flute came with precise instructions on how to break the wooden instrument in for the first month or so in order to acclimate it to the moisture from playing, such that the danger of the wood cracking would be minimized. Why do I mention that? Well, perhaps Apple should provide similar instructions to users, explaining how to "break in" the face id feature - what to do, what not to do over the first several weeks in order to ensure that face id security works well. Just a thought. Never thought I'd compare a high quality phone to a high quality musical instrument, but there you go.
I'm know I'm WAY late to the game on this one as it's probably had 50 replies by now, but it made me chuckle. I can't help but think of the Titanic here. When it comes to promised security, I'm not 100% convinced that 'positive thinking' is the key component.
I would guess that Face ID is THE feature that most distinguishes this phone from others in the eyes of most consumers. My top 2 questions about this phone are 'How reliable is the facial ID at unlocking my phone quickly?' and 'How secure is Face ID at keeping others from doing the same?'
If these couple of videos are isolated incidents over the next few weeks, then we have a winner. If more and more of these videos surface it may give people pause in their decisions. When spending $1K+ for a phone, we can only expect people to put the device through its paces! This is fair game in my mind.
I could be wrong, but I think some siblings might be able to scan one face for the first scan during Face ID setup. Then scan the other face for the second scan. Then, Face ID would probably accept either face. 
This should be pinned to the top so it can smack some common sense into ignorant skulls. But the price is basically what has caused this "controversy". If this phone was the same price or even 50 bucks lower than the Note, this wouldn't be an issue. Actually, prepare for a titanic-sized uproar about any supposed minor grievance because "OMG 1000 DOLLARS!"
I think they are considering that, the problem is probably that the technology necessary to put fingerprints into the display is not there yet.
Nope. They've stated they always intended going through with Face ID as the next step. From next year, Touch ID will officially be nixed.
Um yea. If you lose it even if it worked from the first minute you used it you still screwed. What’s the difference?
What’s the frequency Kenneth?
These videos are both fake!!!!
I Also did this with my friend. We don’t look anything alike completely different facial features.
Here is how you do it....
Go and reset your facial recognition.
When you are prompted to set it up again. Scan your face. Then on the second time it asks for one more scan hand the phone over to a friend and have them scan their face.
It may ask again after that. Scan yiur friend face again. And then yours again.
Boom now two people can open the same phone.
They are trying to get views on their YouTube channel.

What good would that do using the Touch ID, they would still just use the camera. Unless you’re suggesting that both methods must be used to unlock? That, would be plain stupid.
That would b lame. You guys bitch that you want Apple to be progressive then deal with the early adoption issues and chill.

Thank you, that was my first guess. Nice of you to confirm.

This might actually be good news for people who were complaining about not having more than one FaceID. Hidden feature i would say and now problem solved lol
The funny thing is- people keep saying "then use a passcode" if you're not happy with Face ID. Really? Has anyone tried using their phone all day long- or week after week using just a passcode? It's way too annoying (after getting used to Touch ID)
I have my old iPhone 5 I use occasionally as a backup (no Touch ID on ip5) and entering a passcode all the time throughout the day sucks BIG TIME.
Buying $1400 phone and then being stuck in passcode land is not an option.

MacRumors needs to update the info on the first set of brothers. They set it up to fail (probably unintentionally). This is what he said in reddit:
https://www.reddit.com/r/iphone/comments/7anj9f/comment/dpcih16
They clearly don’t understand how Face ID is set to learn the face, so they set it up to admit both of them from the get.
This is a non-story.

So , any proof how well this machine learning works? I get the theory. It's quite sad how easily it is for us "humans" to tell the diffence straight away, and yet we use the excuse that the machine will learn .... over time. That's not how a secure system works .
Yeah, well if the machine is this dumb out of the gate, I don't have much hope for the learning that will come down the road...
Maybe we’re just dumb believing this to be real? Ever think of how they used both faces while setting up the Face ID?
