MacID

A look at akshith.io

MacID brings Face ID-like authentication to Mac computers. After you reach the password field and press return, MacID uses your Mac's camera to recognize your face. If it matches what it has stored, you're logged in; if not, the password bar wiggles like a wrong password entry.

The system integrates into macOS authentication through PAM (Pluggable Authentication Modules), running a PAM module at the lock screen that communicates with a desktop app in your menu bar. The desktop app holds the actual face recognition service and camera permissions. Face recognition uses a pretrained model that achieves 99.5% accuracy with 0% false acceptance rate on a standard dataset.

MacID preserves your Keychain functionality by securely storing your password in the Mac's Secure Enclave after you provide it once, then using it to unlock your Keychain after face authentication. You can still use your password normally at any time. Like Touch ID, MacID requires your password after restart or hibernation before face unlock works again.
