Why does it depend on python2…?

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.

Last time I tried it, I wished the DM indicated its processing my face and also if it failed, and a button to retry. Also will the model be fooled by an IR photo of my face?

I did have fun opening the IR camera feed and seeing objects of various opacity in visible spectrum behaving differently in IR.

This isn't "Windows Hello style." This program extracts features from a 2d image instead of doing depth reconstruction first. This makes it easy to fool with a piece of paper.

Also this only handles user authentication unlike on Windows where it can be usedpasskey. disk encryption and for passkeys.

Edit: This program also saves the landmarks of your face into a file in plain text when it gets added.

yeah its more of a taster demo. I wish them luck in developing it properly though... I'm doing an ubuntu MOE for a corp atm and man, I really miss the windows hello logins.

Really? When I tried on an hp spectre 5 years ago it made the hell sensors make a horrible clicking sounds and the LEDs glow red. I assumed it was doing something with depth analysis.

Main dev here: If you're on the 3.0 version you'll be able to install howdy-gtk, which will show a popup at the top of your screen when authenticating.

You can also enable "rubberstamps" which require an action from you like nodding yes to confirm authentication and making it harder to fool. As noted in the readme though, Howdy is never going to be 100% secure

Depth reconstruction with IR cameras in laptops today is incredibly hard. While the camera itself is exposed in Linux as a USB camera, the sync with the IR emitters is completely lost. Because of this we cannot extract a "left" and "right" lit image reliably as Windows hello does

Is 'Hello' and those kind of biometrics generally enabled at $CORP? The ones I've gigged at have been the polar opposite of using it, due to regulatroy requirements. Even disabling macos fingerprint reader company-wide, which is prerry darn good imho.
