SUMMARY Currently, the grace lock timer of the lockscreen is hard-coded in the qml file of the lockscreen (!!), e.g., see /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/LockScreenUi.qml). I believe this does not make any sense and provides zero security improvements w.r.t. to not have it at all, as it is enough for the user to change theme (!) and have this "security measure" automatically disabled. Either use PAM, or make it customizable, or simply remove it altogether, as it is just frustrating to wait for 3 seconds before writing again the password, knowing I am loosing time without gaining any security. EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
FWIW changing lock screen "themes" at runtime is no longer supported in Plasma 6.1, so that element won't be a problem anymore. *** This bug has been marked as a duplicate of bug 407473 ***
