I use multiple systems, and all seem to have some kind of way to ease the use of password prompts:
On MacOS you can use the fingerprint reader, or the Apple Watch to authorize operations (yep, even sudo)
On Windows, Windows hello allows you to authorize using a fingerprint reader or specific camera setup
Fingerprint readers are not as widely supported in Linux as in Windows because of vendor limitations (they just don’t care).
Is there any other recommended way to authorize operations on a desktop computer using something similar to the other systems? (Fingerprint readers, Bluetooth auth, etc)
It really depends on the age of the hardware if fprintd is going to have support for the sensor. I have a ThinkPad T80s and fprintd doesn’t cover my sensor.
I would probably stick with Bluetooth because it generally works fine across all my machines, while the fingerprint sensor is super finicky and this is the third machine I’ve had this issue with.
