It seems that in the code of the betas of Big Sur macOS References to Face ID have been seen. This means that the next Macs (we assume they are already ARMs) will have facial recognition unlock. The truth is that Apple has taken a long time to implement it on Macs.
It is a very comfortable system for the user and very safe that Apple introduced it for the first time in the iPhone X back in November 2017, and that it has continued to maintain even the current iPhones. So we can finally start our Macs in three ways: typing the password, with the Apple Watch, and hopefully with Face ID.
As discovered in the code for the macOS Big Sur beta versions, the upcoming Macs They will be able to have a login without having to type the password or wear an Apple Watch on their wrist. They can be unlocked with Face ID, as we do on our iPhones from iPhone X onwards.
Features discovered with names like "PearlCamera", "FaceDetect" and "BioCapture"
Adding a TrueDepth camera system and Face ID to Macs would be the most logical thing to do, given the good results this system has in iPhones and iPads Pro. References to Face ID have been found in the latest beta version of Big Sur, including a code extension to support a function named "Pearl Camera«.
"Pearl" is the code name that Apple has always used for Face ID and the TrueDepth camera system since the feature was first released on the iPhone X three years ago. There are also references with the names of «FaceDetect" Y "BioCapture»Within the extension, and those names certainly suggest a TrueDepth camera feature for Mac.
Although said implementation It seems very logical and physically possible due to the large screens of the Macs and MacBooks, it is not known if the next Mac that the company launches will come with Face ID. Until now, no rumors had appeared about it. We'll see.
