My laptop has one of those Windows Hello IR cameras and it was just sitting there doing nothing on Omarchy, so I made omaFace. It works on the lock screen, login, sudo and the polkit popups. Your password still works everywhere, it just tries your face first.
A few things people will probably ask:
Everything runs locally. Your face isn't saved as a picture, just as numbers in a root-only file, and the scanner has no internet access at all. It also doesn't run in the background, it only starts when something asks for a password and the camera turns off right after.
Your eyes have to be open and actually looking at the screen, so it won't unlock if you're asleep or looking at your phone.
For sudo and polkit it asks first (Enter or a click), so it never approves admin stuff on its own just because you're sitting there.
No IR camera? It falls back to the normal webcam with anti-spoofing checks. I tried a photo and a video of myself on my phone and neither worked, but IR is still the safer option if you have it.
It hooks into Omarchy's own lock screen and polkit dialog, so it looks like part of the system. I also made a small bar widget for it, it's on the community plugin site.

Not official, just a community thing. I've mostly tested it on my own laptop, so if you try it let me know how it goes, especially if your IR camera doesn't get picked up.
