Howdy provides Windows Hello™ style authentication for Linux. Use your built-in IR emitters and camera in combination with facial recognition to prove who you are.

Using the central authentication system (PAM), this works everywhere you would otherwise need your password: Login, lock screen, sudo, su, etc.

Howdy is currently available and packaged for Debian/Ubuntu, Arch Linux, Fedora and openSUSE. If you’re interested in packaging Howdy for your distro, don’t hesitate to open an issue.
