Upon entering a wrong password the system shows "Login failed" or "Unlocking failed", whereby the password field is locked for about 4 seconds. I don't need 4 seconds to realise what this simple message means, it's quite obvious I made a mistake so I want to retry immediately. Note that the system behaves slightly different when providing a wrong password on initial logon or at unlocking: - A wrong password at initial logon results in a locked password field for 4 seconds, after which the message "Login failed" is shown. - A wrong password at unlocking results directly in a message "Unlocking failed", after which the password field is locked for 4 seconds. The preferred solution to this is to show either the "Login failed" or "Unlocking failed" message directly (which could be faded away after a few seconds if the user takes no action), and NOT to lock the password field so the user can try again immediately. An alternative would be the Windows 10 approach: upon entering the wrong password a message is shown with an OK button; it gives perfect feedback of what went wrong and by hitting Enter you can try again immediately.
Thank you for the bug report! However Plasma 5.24.7 is no longer eligible for support or maintenance from KDE; supported versions are 5.27, and 5.27 or newer. Please upgrade to a supported version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one. If you need support for Plasma 5.24.7, please contact your distribution, who bears the responsibility of providing support for older releases that are no longer supported by KDE. If you can reproduce the issue after upgrading to a supported version, feel free to re-open this bug report.
I get your point, but we're talking about the (latest) Kubuntu LTS release here, 22.04. Anyway, I just reproduced this on KDE Neon with KDE 5.27.9.
