My Face Unlocks My Brothers X

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...

Maybe we just can’t see how similar we are then.

Surely this means any twins can unlock each other’s devices?

Yeh sure! Not sure how to show it happening but here’s a picture of us from a couple months back.
Granted that Phil Schiller stated that twins will likely reduce the security of Face ID, and I know you stated you are not twins, but you do have a strong resemblance given the circumstances.

QUICK... sign an endorsement deal with Samsung to show weakness of their competitor.

In seriousness, you guys are the 1 in a million Apple mentioned. (I imagine the real life number is far lower.) You really are crazy close to identical for 4 years apart.

Microsoft made a big deal about their IR sensor being able to tell twins apart and there are lots of videos showing that it can... I wonder why Apple couldn’t match MS in that respect? Maybe it’s about speed or maybe MS is helped by online processing whereas Apple secures it on the phone for privacy.

Edit to clarify: their sensor in Surface Pro devices. Which works really well by the way.

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.

Pretty sure I remember Apple saying that both twins, and siblings that share a strong resemblance were both a problem for FaceID.

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

Yup. From the photo, they look like identical twins honestly. Not surprised FaceID is unlocking.

my brother and i are often assumed to be twins though we're 18 months apart..
i'll see him next weekend in Miami and will be sure to see if he can unlock my X with his face.
