What is FaceID
Face ID is Apple's advanced technology for authentication and security of the iPhone and iPad Pro. Debuted in November 2017, with the presentation of the new iPhone Biometry.
Today, Face ID remains the main and most advanced biometrics method on the smartphone market, ensuring biometric authentication with greater security and intuitiveness than previous technologies. In addition to unlocking the device, Apple's facial recognition can also authenticate Apple Pay purchases, as well as download and sign apps from the App Store.

How does FaceID work?
At first glance, it may seem strange and uncomfortable to use an iPhone with a huge notch at the top of the screen. The reason is simple to explain, but it involves a lot of engineering behind the scenes: the TrueDepth camera system. He is responsible for the operation of Face ID. Its function is to accurately map the geometry of the face and therefore needs to occupy a larger part of the screen than a common selfie camera.
To better understand the magic of TrueDepth, its advanced technology – which integrates hardware and software – accurately reads facial data and projects thousands of invisible points to develop a depth map, as well as improving its accuracy with an image. facial infrared. This definitely prevents a simple photo from unlocking your iPhone or iPad Pro.
This feature is possible thanks to part of the Neural Engine, present in the A11, A12 Bionic, A12X Bionic, A13 Bionic, A14 Bionic and A15 Bionic chips and protected by the Secure Enclave. Thus, the depth map and infrared image can be quickly calculated for data comparison.
The intelligence of the feature is such that Face ID can adapt to changes in a person's phenotype, that is, even if you wear makeup or grow a beard, you can still use facial recognition. Furthermore, if there is another type of more sudden change to the face, simply use the unlock code to confirm the identity and Face ID will update the data.
And it's okay if the user is in a light or dark environment, and still wears a hat, scarf, glasses, contact lenses or other similar accessories on their face, Face ID can still recognize them and authenticate the data. . One of the only drawbacks is the use of a mask, which has already been resolved with the iPhone 12 (or later) updated from the iOS 15.4 system.
Can you bypass Face ID?
With the numerous attempts to copy Apple's feature on competing smartphones, consumers may become suspicious about the security of the original feature itself. After all, would an average person be able to bypass Face ID using a photo or other similar feature?
The answer is no. There is no way for an ordinary person to use alternative methods to trick Face ID and access user information. This does not mean that the technology is infallible, some studies have already shown that it is possible to bypass biometrics and unlock the device. However, ordinary people do not need to worry, in general the chances of this happening to ordinary people are small.
