Mom's iPhone X unlocked via FaceID by son

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. That’s what the Malik family found out when 10-year old Ammar unlocked his mom’s iPhone with no issues at all.
And he didn’t even need a fancy 3D printed mask as some security researchers have used to get past Apple’s new biometric security. He has his mom’s 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 doesn’t think so – he can unlock his mom’s iPhone X but not his dad’s.
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 brother’s 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 doesn’t know his mom’s PIN.
