Hardware authentication

Fingerprint authentication

A lot of laptops come with a fingerprint sensor to do authentication. You can use this with OmarOS by running Setup > Security > Fingerprint in the OmarOS menu (Super + Space).

That'll install the fingerprint package, collect your print, verify it, and you'll be set to go using your fingerprint to unlock from the lock screen (which you can trigger with Super + Ctrl + L), enter sudo mode, and authorize system prompts.

Once the lock screen has turned the display off, the sensor rests to save power, so wake the screen with any key or the touchpad before touching it.

When your laptop lid is closed, the fingerprint prompt is automatically skipped, so you go straight to the password prompt instead of waiting on a sensor you can't reach. If you otherwise need to work on an external keyboard that doesn't have a sensor, just hit CTRL + C, when you're prompted for your fingerprint during sudo.

You can remove the fingerprint authentication under Remove > Security > Fingerprint in the OmarOS menu.

Fido2 authentication

If you're using a Fido2 device, you can set it up for sudo authentication using Setup > Security > Fido2 in the OmarOS menu (Super + Space). It covers sudo and system authorization prompts, though, not unlocking your computer.

You can remove the fido2 authentication under Remove > Security > Fido2 in the OmarOS menu.
