At a first glance, it seems like a well done authentication system that handles video capture, integration with PAM, the workflow for managing faces/users, etc.

As models evolve, they could be integrated without changing the other components.

Also, I'd be curious to see how it compares to, say, Windows Hello. The nice thing about it being open source is you can change the confidence threshold for matching a face, and see the impact.

AFAIK Windows hello uses an array of IR sensors to map the contours of your face, which is why "a well printed photo" doesn't fool it. this on the other hand, is based on face recognition and identification in the video feed from your webcam.

It really does not, it's simply identifying you from a picture: https://docs.microsoft.com/en-us/windows-hardware/design/dev... Notice how Microsoft shows how Hello can't be fooled by phones or by a picture. Howdy uses the same IR camera of course and thus would also not be fooled by that picture. Some (industrial) printers DO print in the IR-spectrum and can fool both.

thank you! I learned a lot from this comment... including that it's possible to print the IR spectrum. Amazing.
