Earlier, when Apple introduced FaceID biometric authentication technology for iPhone X, a code snippet called “PearlCamera”Was found in the update iOS and now developers have found references to "PearlCamera" in macOS Big Sur Developer Beta 3.
As he says 9to5 Mac, The beta version of macOS also revealed codes such as "FaceDetect" and "BioCapture" which indicate that Apple is working to introduce the biometric face unlock option in MacBook Appliances.
Of course the whole project is still in the testing phase and it is very likely that Apple will need some time to finally bring it to Mac devices.
FaceID will definitely add an extra level of security to MacBooks and make it even more convenient for users to unlock their devices.
One of the best applications of this technology could be seen in iMac, as the MacBook Air and MacBook Pro already have the TouchID biometric authentication system built into their built-in keypad. Since iMacs do not have built-in keyboards, FaceID will be especially useful on them.
The addition of the machine Neural is definitely something that will help in the integration of FaceID, as it is one of the main components for the analysis of facial data. Recently, Apple announced that it will stop using its chips Intel and will start using her own.
As speculation suggests, FaceID could be released along with the first MacBook to use Apple Silicon.
