Of all the cool new products mentioned during this year鈥檚 famed Apple Event, people are by far most intrigued by the mysterious iPhone X. With an all-screen design that ditches the need for a home button, a cool new suite of photo taking options, the ability to turn yourself into an emoji with Animoji, and some pretty spiffy new augmented reality capabilities, it鈥檚 definitely not hard to see why people are already saving their pennies for this expensive new smartphone.

But there鈥檚 one new feature of the iPhone X that鈥檚 causing a few Apple fans to question whether shelling out a whopping $1,000 for the latest smartphone will be worth it. Along with all their other advancements, the iPhone X will ditch the fingerprint scanner of its predecessors and opt for facial recognition software instead. According to Apple, Face ID is 鈥渁 powerful and secure authentication system that鈥檚 even more convenient than Touch ID.鈥 In order for Face ID to work, it uses the iPhone X鈥檚 TrueDepth camera system to project invisible dots on your face, read your unique facial map, and hopefully unlock your phone. Obviously people have a few concerns about this new system 鈥 here are a few questions that you may have about Apple鈥檚 new Face ID system, answered.

Q: Will Apple store this sensitive information on the cloud?

A: If facial recognition software is the way of the future, the last thing you want to happen is for Apple to send your face scans up to the cloud to be hacked and shared for profit. Luckily, Apple has made it very clear that this information will not be sent to the cloud and will instead store all of your face data on each individual device 鈥 AKA the same way they stored all of our fingerprint data with Touch ID.

Plus, there are other ways that Apple is making sure that our face scans stay securely on our individual iPhones. According to the Verge, 鈥淚n broad strokes, Face ID works the same way Touch ID did: The system reads your face (or fingerprint), then creates a partial version to compare against future prints. It鈥檚 a purposefully incomplete picture, so even if you could extract the data, it would be impossible to fully reconstruct a person鈥檚 face.鈥

Q: What happens if you decide to grow a beard or get a drastic new haircut?

A: Face ID is a technology that is designed to grow incrementally 鈥 meaning it theoretically won鈥檛 matter if you decide to rock some glasses or get a buzz cut. Of course, without access to the technology ourselves, we won鈥檛 be able to fully comprehend how intuitive their new A11 Bionic chip is at using machine learning to recognize changes in your appearance until the official release date on November 3.

Q: Can a printed photograph fool Face ID?

A: In his Apple Event presentation, Philip Schiller noted that the device can鈥檛 be fooled by a printout photograph or even a lifelike Hollywood-grade mask. Since the original launch of Touch ID could be hacked with a little Elmer鈥檚 glue, we鈥檙e happy to hear that Apple is stepping up to protect our security 鈥 especially since it鈥檚 not that hard to find anyone鈥檚 picture on Instagram, Facebook, or LinkedIn these days.

Q: Are there any people who shouldn鈥檛 use Face ID?

A: Unfortunately, the answer is yes. Despite testing the system on a diverse set of a billion different photos, there are still some individuals who should still probably avoid using Face ID regularly. In his address at the Apple Event, Philip Schiller joked about evil twins cracking the Face ID system 鈥 but it seems like Apple isn鈥檛 actually joking when it comes to twins.

According to Apple鈥檚 support page, 鈥淭he probability that a random person in the population could look at your iPhone X and unlock it using Face ID is approximately one in a million.鈥 However, 鈥淭he statistical probability is different for twins and siblings that look like you and among children under the age of 13, because their distinct facial features may not have fully developed.鈥 If either of these are concerning for you, Apple recommends using a passcode to authenticate your login instead.

Q: Will Face ID make it easier for our iPhones to turn on when we don鈥檛 want them to?

A: One of the biggest questions skeptics have about Face ID is that the new technology will make it easier for others to gain access to their sensitive information by simply requesting that they look at their iPhone X. To this, Schiller says, 鈥淚f your eyes are closed, if it鈥檚 not lined up, it鈥檚 not going to work.鈥

Q: Can you disable Face ID?

A: Yes. If you are in an emergency situation and would like to immediately disable Face ID, pinch the side buttons to put the phone into shutdown mode. Just like the current system, it will require a passcode to unlock for your first attempt after a full shutdown. If you would like to disable Face ID permanently (perhaps to dissuade your evil twin?) you can do so in Settings.
