Linux Hello provides facial recognition based authentication for Linux. Use your built-in IR emitters and camera 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.
sudo apt install g++ libpam0g-dev libopencv-dev libdlib-dev libboost-program-options-dev nlohmann-json3-dev libatlas-base-dev libsqlite3-dev libcereal-dev
