Apple’s iPhone X is now finally a reality following the announcement of the new flagship this past Tuesday, and with so many facets to the device, there are still plenty of questions to be answered as well as new ones that are popping up as we learn more about it.

Without doubt the most talked about aspect of the new iPhone X is Face ID, the biometric security system that will replace Touch ID when the iPhone X arrives on November 3rd.

Whenever there is a major shift in the iPhone we are used to, such as the removal of Touch ID and the arrival of Face ID, there will always be a learning curve as well as a number of questions surrounding the move. This is most certainly no different, and we have three or four little tidbits that we think you may have either missed during the whirlwind that is the past few days.

So without further ado, let’s jump into it.

Face ID will only recognize one face

This is both a good and a bad thing in a way, but whereas Touch ID could register a bunch of fingerprints, Face ID cannot. That means that you cannot have your spouse’s face registered as well as your own, which can be great for security but not so much for emergencies. It might be worth making sure they know your passcode, too.

Apple has been all-in on face recognition for a year

Previous rumors had suggested that Apple had made the decision to ditch Touch ID on the iPhone X fairly recently, but one commentator believing is that this is not the case. Replying to a question regarding the possible return of Touch ID on Twitter, John Gruber said that it was very unlikely and that it was his “understanding is that Apple has been all-in on Face ID as the replacement for Touch ID for over a year now.”

Face ID works with most sunglasses

Well, maybe not with all sunglasses, but most. That’s according to Apple’s Craig Federighi who was replying to an emailed question from a fan. In addition to sunglasses, Apple has already confirmed that Face ID will work with all kinds of specs.

Temporarily turning off Face ID is easy

Replying to the same emailer, Federighi also said that if you find yourself in the unfortunate situation of handing an iPhone X over to a robber or a cop, you can “grip the buttons on both sides of the phone when [you] hand it over, it will temporarily disable Face ID.” Hopefully we will never have to try that particular feature out!

No Face ID for under 13s in third-party apps

According to Apple’s App Review Guidelines for September 2017, the company says that third-party apps implementing Face ID authentication must require under 13 year olds to authenticate locally via passcode instead of their face.
