OP. I'm curious. Have you tried Google Photos? Can google photos differentiate you?
I would love to know that as well, as Google somehow distinguished me when I was a BABY! I'm 27 now, and i only had it "learn" a photo of me from a picture from a few years ago. It was able to do this as well with my brother

Google doesn't use a 3D camera. I'm not sure how Google would be relevant.
Google photos can distinguish each person in a photo, if you trained it to know who is who. It can go through all of your albums and pull pictures of myself, Dad, Mom, Grandma, Bob, Sally, etc. Facebook can do this as well if you tag yourself or someone in a photo.

Ah ok, well if it makes any difference we haven’t had any suggested tags on each other’s faces before on Facebook or Apple photos/iPhoto.

I’m not sure how this relates but you know how one of the new features of os11 (or was it 10 point something?), is that the camera roll can scan through your pictures and pull all those who have x in it or all those with y and then make a mini album within? Caterogized as people?

I have pictures of my family and friends and this includes my mom and older sister (when we were younger people would compliment my mom and say we’re all sisters).

Facial recognization placed a sole picture of my mom that I recently took, with a picture of me (someone else took) as well as various selfies ( :D ) as one “person”. My older sister funny enough wasn’t in it.

You guys should see if you have the same problem with a Samsung phone. That would be VERY interesting to see.

My brother is getting an X by the end of the month. I’m interested in seeing if I can trick the FaceID. There’s a 4 year age difference between us and I really don’t think we look that much alike, but people have mistaken us for twins.

I can confirm this issue....

It worked for me and my brother, and we don’t look as similar as you guys! We both have thick eyebrows and a big nose, but that’s it!

My brother has the new Samsung that works with the face recognition and I can’t get into his phone!!!!! Grr

Above guy said it earlier. Not sure if he meant facial or Iris though.

Face ID is powered by machine learning. It scans your face and updates its model accordingly every time you attempt to authenticate using it. It learns from times when it doesn't unlock, and you then type the correct password. It gives heavier weighting to the best scans and, of course, gets to know you better with time. The first two scans in setup will provide some basis for your initial interactions but will quickly become insignificant in the model. If you manage to get in after a month or so of use by your sibling, then be concerned.

Not with iris scanner which has a false positive rate of 1 in 1.4 trillion (about 1.4 million times stronger than Face ID).

Face ID failing the evil twin test means it's susceptible to being fooled by a good disguise.

It's already been tested on YouTube where twins have unlocked their iPhone X's with Face ID. But for the majority, they don't have twins , which would be one out of 1 million to unlock Face ID.

If you have a sibling , with similar appearance , and not even a twin, it's not 1 out of a million.

Who has siblings right ? At least those foreigners from outside the family are 1 out of million . Way I see it , touchid is far more secure , given you have a lot more chance of a close sibling living with you .... ;)

I'm not sure what tangent you're going on, nor is it related to my initial point behind some random individual trying to unlock your iPhone with Face ID. But my point behind my post was Phil Schiller stated that if you have a twin, Face ID will not be as secure as it could be. However, based on some random stranger who will try to use your iPhone to unlock it, which is one of a million.

Just saying that it's new tech, and I would not take on face value what Phil says. Two days with mine, I've put the sim back into my 7 plus so can compare ... faceid works well , but damn homebutton/touchid is so refined and feels natural . Pros / cons

So how has faceid been for you ? For my touchid has a higher hit rate, never misses while I've had a few faceid fails

My brother collected his white 256GB iPhone X this morning and first things first - it's beautiful! Definitely a fresh design and the screen really is excellent. He's spent most of the day playing with the portrait modes which are a game-changer for him and his business.

Now, FaceID. For the most part it's great and is a realistic alternative to touchID. After setting it all up and using it throughout the day he claims that it's a more seamless process than touchID and feels like a step in the right direction - until I picked it up and it logged me straight in.

My brother and I are similar looking but being 4 years apart we are far from identical twins. How is it that FaceID can't differentiate us? After trying with a few friends and family members the system works as it should with them, just us two!

Any others with similar issues? Is this worth a trip to the Apple store or is this just a freak instance where we have some similar features that are used for identification?

Guess the system just lets any good looking geezer in...
Same happened to my brothers iPhone X and my face but I realized it only happens if you use the numerical passcode a couple times. Then the Face ID unlocks with my face as well.

You are effectively training it to recognize both of your faces as if they were the same.

Although I've read according to Apple it only supposed to recognize and learn one face

That’s true. However if faces closely resemble each other in rare cases Face ID can be “trained” to recognize both.

The reality is, if you have a sibling or family member that has strong resemblance to the iPhone X owner and can unlock it, I don’t think it poses that much of a security risk unless your family member can’t be trusted or Widely has access to your X. But given that twins is a rarity and other family members that can successfully unlock the iPhone X, I would say it’s still fairly strong security method to prohibit any random stranger from unlocking it.
