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
Edit: follow up on an old post in case someone stumbles across it - I needed to install libpam-fprintd
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
