Description andy 2024-04-30 16:05:47 UTC

SUMMARY
Normally at night I do Super+L to lock my screen, then turn off my monitors. In the morning I turn on my montiors and move my mouse to see the password prompt. Today I instead of a password prompt there was a "Unlock" button. When I clicked it, it unlocked my session without prompting for my password.

It sounds similar to this https://bugs.kde.org/show_bug.cgi?id=484363 but clicking the button unlocked my session, without asking for a password. And similarly, it doesn't happen every time (I haven't reproduced it by locking/unlocking since just observing it now).

The logs had this very sus line: kscreenlocker_greet[582024]: file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/NoPasswordUnlock.qml:26: ReferenceError: tryToSwitchUser is not defined

STEPS TO REPRODUCE
1. Lock screen at end of day, turn off monitors.
2. Next day turn on monitors, move mouse.
3. Observe "Unlock" button. Click it.

OBSERVED RESULT
Clicking "Unlock" unlocks the session without asking for a password.

EXPECTED RESULT
You should never be able to unlock the session no password or an invalid password.

Comment 1 andy 2024-05-02 14:35:38 UTC

After two more nights, unlocking my computer on May 1st had the password prompt as expected, but today May 2nd it had the passwordless "Unlock" button again. Clicking it unlocked my desktop with no password needed :\

Here's from the logs this morning when turning on my screens, and then clicking the unlock button a minute later:
