Show HN: MacID – Bringing Face ID to the Mac

Category: security

Tags: macos, pam, face-recognition, authentication, swift

Score: 5.8/10 (Innovation: 5, Technical: 7, Documentation: 6, Utility: 5)

MacID brings face-unlock authentication to the macOS lock screen by inserting a PAM module that recognizes the user's face before falling back to the password. It is an interesting hack of Apple's undocumented PAM stack, though its security is limited by webcam spoofing and non-commercial face model licensing.

Target audience: macOS power users and security hobbyists
