Since the announcement, however, reporters, advocates, and iPhone users have raised concerns about how Face ID could impact Americans' fundamental right to privacy, speculated on the ways in which Apple could use faceprint data in the future, and questioned the quality and security of the technology.
There's distrust over biometric tech's ability to protect users' security and privacy.
Will you be buying an iPhone X when it arrives in November?
Face ID uses "TrueDepth" camera system made up of a dot projector, infrared camera and flood illuminator, and is powered by A11 Bionic to accurately map and recognise a face.
Face ID, which uses a Kinect-like system to scan the user's face and only lets a matching faceprint unlock the phone, is being treated with some skepticism in the tech community. Face ID's also got to demonstrate it's a suitable replacement for Touch ID, an authentication method now understood and approved of by many consumers.
He also wants to know whether the Face ID will recognize different genders, races, and ages.
Apple is bucking its traditional naming convention by calling the new phones iPhone 8 rather than 7S.
The phone's quad-LED True Tone flash has something called Slow Sync, which uses a slow shutter speed along with a short strobe to create a more uniformly-lit photo.
Where did the one billion images that were used to train Face ID come from, and what steps did the company take to ensure the system was trained on a diverse set of faces?
Also slowing the spread of the technology has been the daunting technical challenges of accurately analysing faces in anything less than optimal circumstances. Before the presentation, many Apple employees were playing with the device, trying to see if the FaceID works the way it was meant to.
I am left wondering, however, about the relative insecurity of this accommodation. According to Apple, it's faster than a Touch ID fingerprint sensor and is only inaccurate one in a million times.
The eye is a big concern for most people in the blind community.
The event was particularly unhelpful for Apple because many have taken it as evidence that the company's facial recognition technology isn't actually read.
"However, I am sure that is not the reaction Apple wanted". Facebook past year acquired FacioMetrics, which let smartphones analyse facial images in real time, and in 2015, Snapchat bought Looksery, a startup that applied filters to users' faces. It just seems like a bit of a waste of effort for us. For instance, the system could be tricked eventually by showing them a photograph of the person's face-the system thought it was the user's real face and unlocked the phone from the secure lock screen to the home screen which allowed anyone access to the phone's apps and data.
