Howdy — вход в Linux по лицу

★ 7.7K

Howdy is an open-source tool that brings Windows Hello-style facial authentication to Linux, using the built-in IR emitter and camera. Reach for it when typing a password dozens of times a day feels like the most annoying part of your workflow; when you want to confirm sudo with a glance instead of a passphrase; when your laptop already has an IR camera sitting unused. Recognition runs in infrared light — low-light rooms are fine, and a phone photo won't fool it. It hooks into PAM, so it fires everywhere Linux would otherwise ask for a password: login screen, lock screen, sudo, su, and more. Written in Python 3.6+, built with meson and ninja; ready-made packages are available for Ubuntu, Debian, Arch Linux, Fedora, and openSUSE. The CLI command howdy covers adding face models, listing or removing them, disabling the feature, and testing the camera. The direction is biometric login in place of a password — not disk encryption or network security. The project authors explicitly warn that facial recognition is a weaker factor than a password on its own; on machines with sensitive data, combining both methods is strongly advised. Works on any supported Linux distro with an IR camera; not suitable as the sole authentication method for high-security environments.
