Fingerprint reader support
Thanks for making this very polished theme. Currently, there is no prompt such as "swipe your fingerprint to login" like the stock antergos theme for webkit2-greeter. One has to press enter while in the password entry box to activate the fingerprint reader. Also, if fingerprint authentication fails, it does not fall back to the usual password authentication. I'm on Arch.
I dont really understand what i'm supposed to do, "One has to press enter while in the password entry box to activate the fingerprint reader" ? I mean, i don't think there is an API in webkit2-greeter for it, is there? Thought fingerprint devices just typed password themselves, i'll try to figure how it works, but can you explain more in details what you do on the regular antergos theme, and what you are doing to make it work on my theme ?
I feel like this has something to do with PAM, but I'm not entirely sure what the issue would be. Trying to configure howdy to work with lightdm (with light-locker as the screensaver) currently is not working as intended, making me put in the password, then my face instead of just allowing one or the other.
It's unclear if this is a limitation of lightdm, webkit2 greeter, or this theme to me, and I think the fingerprint is an error in the same manner.
Edit: This issue is probably the same thing.
@WingofaGriffin it's not. #33 refers to HTOP which is an One time password algorithm, which mean you have a generator app/device that generates a different password each time you login. It's similar to standard time based 2FA (which is actually TOTP) but instead of the password changing based on the current time, it changes every time a password used.
Next month I am going to get a new laptop and it happens to have a fingerprint reader. Perhaps I can do some digging then and help with the resolution of this problem.
Ah that's a shame. I'd do some testing myself if my fingerprint reader was supported (damn Synaptics!)
I don't know if someone still cares about this, but the issue is still open, so:
The fingerprint login worked for me by adding
auth sufficient pam_fprintd.so
to /etc/pam.d/system-local-login (see https://wiki.archlinux.org/index.php/Fprint#Configuration).
@scrouthtv does it still work for you with only that line added? What does it look like? For me it does not have any effect on the greeter, I only have password login available.
As instructed by Archwiki, I had the following lines in /etc/pam.d/system-local-login,
auth sufficient pam_fprintd_grosshack.so
auth sufficient pam_unix.so try_first_pass nullok
auth sufficient pam_fprintd.so
I was unable to log in using this theme -- I needed to boot into runlevel 3, and change the greeter back to slick-greeter (which works well with fprint).
