Ask the Fedora maintainer? The README instructions only say Python 3. The OpenSUSE package's specfile only says Python 3, and to be sure I tried installing it and it did not pull in Python 2 packages. Actually even the Fedora package's specfile only says Python 3, so I'm not sure why the README says that it still needs Python 2. Edit: Okay, the explanation is in this commit message: https://github.com/boltgolt/howdy/commit/305e42fc79ef38f66c5... . The dep on Python 2 is from Fedora's PAM module package, not from howdy itself. On OpenSUSE the corresponding PAM module package depends on Python 3 already.

Sadly, looks like no: https://github.com/boltgolt/howdy/issues/521 "Windows Hello uses the two IR emitters to generate a 3D image of your face, and is much more secure. To do this Hello lights up your face with the left emitter on even frames, and uses the right emitter on odd frames. This lights up your face in slightly different angles, which is not possible to be faked by simply printing a 2D photo. Unfortunately Howdy does not have control over these IR emitters and can't use this process"

I was gonna say well, of course you should be able to configure it within PAM to only be used for certain authentication types, but it turns out one of the literally five pages in the wiki covers just that: https://github.com/boltgolt/howdy/wiki/Only-using-howdy-for-... And for anything PAM doesn't handle, since Howdy is just a Python lib/app, it's almost trivial to modify it to do anything else. You could just add your modifications into https://github.com/boltgolt/howdy/blob/beta/howdy/src/compar... (eg, make it autofail if a env/memory flag hasn't been set after first login, same with storing an inactivity flag, etc. Looks like the author is responsive taking pull requests, so you could even do it properly and get it upstreamed even: https://github.com/boltgolt/howdy/pulls?q=is%3Apr+is%3Aclose... As for appropriateness, it's fine if it

's not your cup of tea, but with 3.6K stars and 220 forks, obviously it works great/is useful for a lot of people so I'm glad that the author released and maintains it, even if it's not for everyone.

I have the same laptop with the 4K IPS display and the AMD 5850U, and I am pretty happy with it. On Ubuntu I had to install the Wi-Fi driver manually [0], tweak the grub config to make the screen brightness control work [1], and install gnome-screensaver to make suspend/resume work properly. Maybe things would work better out of the box on Pop!_OS? Otherwise, it's pretty good. It does not heat up much compared to the previous Intel laptop I had, and it is plenty fast. I was not able to make Howdy [2] work properly, and the fingerprint reader was not reliable compared to my MacBook, however.
