These implementations really need to also include fingerprint sensor support
Fingerprint is an authentication mechanism, not an authorization one.
It's both.

#13Nice, I just use lxqt-openssh-askpass, but I am on X11. A lighter alternative (for single-text input) would be FLTK. Version 1.4 is really nice, with Wayland support, and they even draw custom window decorations on GNOME. Both Cairo and FLTK should be able to compile with -X; not sure, though, about the status of the Zig bindings.
fltk is c++ based which makes language bindings significantly harder in general. gtk is c based which worked out really well in that aspect.

PAM really needs to be ravamped and support for (among other things) running multiple stacks in par@llel added. This way you could ask for a password OR a fingerprint
Keypassxc does it perfectly.
Everyone doing parallel biometric and password authentication on Linux today is either running two PAM stacks in parallel (which is meta-policy that kind of defeats the purpose of PAM) or just bypassing PAM entirely.

#15Noticed that when I build this it ends up with direct linking against a half-dozen libraries it doesn't actually use, at least on Ubuntu. Fixed it by replacing the linking commands with this:
exe_mod.linkSystemLibrary("gtk-4", .{ .use_pkg_config = .no });
exe_mod.linkSystemLibrary("gobject-2.0", .{});
When building on Ubuntu 26.04, the binary no longer directly links against lib{pango, cairo, pangocairo, cairo-gobject, harfbuzz, gdk_pixbuf, graphene, gio, vulkan}.
Can't create an account on the site so I figured I'd post this here. If you're going for absolute minimalism this seems like another step in the right direction for anyone building on a more 'gratuitous' GTK build (such as Ubuntu's)

Sure, you need to wrap it in C, but there is also `cfltk` that is maintained and used in Rust bindings.
Btw., the difference in memory usage is huge with GTK4. FLTK hello world is ~10M, GTK3 is ~15M, GTK4 is 40M! With Cairo rendering, it's about 30M, but still a lot.

#17Whenever someone writes "with hand-written bindings" I read "will stop working 8 minutes after the next release"
There are tools to generate bindings. They probably meant it as a marker of quality.
And in languages like zig or odin which are quite similar to C in many ways, writing bindings to C code really isn’t bad. It is so easy that I decided to write my own bindings in Odin to sqlite - bindings exist but it really was so very easy that I didn’t want to bring in a generator or another dependency.

ah neat, I wasn't aware that cfltk was already used by rust.

GTK4 memory usage is ludicrous

I'm vaguely considering rewriting PAM in Rust. It's definitely something that would benefit from Rust's extra security and the code quality isn't that great. Nor is the UX. What "among other things" were you thinking of?
