Tim Cook joked that the new FaceID of iPhone X can be unlocked by your twin. But it turns out that your kids can unlock it too. Thats what the Malik family found out when 10-year old Ammar unlocked his moms iPhone with no issues at all.
And he didnt even need a fancy 3D printed mask as some security researchers have used to get past Apples new biometric security. He has his moms genes and that proved enough. Here, watch the mother and son team do a demo:
Apple claims that the chance of a random person unlocking the iPhone X via FaceID is 1 in 1,000,000, compared to 1 in 50,000 for TouchID. That may be true for a random person, but family members obviously have a much higher chance.
Friends of the Malik family say that Ammar looks more like his father though FaceID doesnt think so he can unlock his moms iPhone X but not his dads.
Anyway, it seems that you need to be careful when first setting up FaceID. Doing it indoor at night can mess with the accuracy. When the mom set up FaceID again (in good light this time), Ammar was no longer able to fool the phone.
Earlier, a pair of brothers posted a video of them fooling FaceID but the issue in that case proved to be the PIN one sibling knew his brothers PIN and used it to unlock the phone a few times. Each time you unlock the phone with a PIN, FaceID recalibrates so eventually it learned both their faces.
The Maliks claim this is not the case with them as Ammar doesnt know his moms PIN.
