The KDE 6 announcement says that

On prior versions you chose between either password or fingerprint authentication for the lockscreen. In Plasma 6, both are supported at the same time.

I’ve updated my Neon install, what do I need to do to enable this? I’ve set up a fingerprint through the user settings, but when the screen is locked I still have to use my password to unlock - there isn’t a prompt, and touching the reader doesn’t seem to do anything

    Does it prompt for fingerprint if you enter an empty password? If not, I have done a little looking around and found a source that states the following :

    Add the following two lines to /etc/pam.d/kde :

    auth sufficient pam_unix.so try_first_pass likeauth nullok
auth sufficient pam_fprintd.so

    This configuration allows you to first press enter on the empty password field to be prompted for the fingerprint

      Empty password doesn’t prompt for a fingerprint, and I thought that was the old hacky workaround for Plasma 5 that Plasma 6 was supposed to have fixed?

        Even if it is, I’m unable to find any other solution. It’s at least worth a shot.
        Do be sure to report this bug in the meantime, it’s likely related to pam &/or SDDM.

          Will do if I can establish what the expected behaviour is supposed to be - from the one line on the website I’d expect a “login with fingerprint” button or something, but I might be wrong - so I know what I’m seeing is actually a bug and not me misinterpreting

          Will see if I can track down the original PRs or something, see if there is screenshots or a proposed UI design
