Howdy – Windows Hello style facial authentication for Linux

I use fprintd and it works well with GNOME + builtin Elan sensor. It indeed needs more complex configuration than Touch ID or Windows Hello though.

In Fedora it's (supposed to be) pretty simple. Just go into settings -> users and add your fingerprint. In practice I usually have to use dnf to nuke pam and reinstall it manually for it to start working. But they have a good skeleton set up. Still no predesktop authentication, though.
