Inspired by https://hexatomium.github.io/2017/02/15/windows10-clipboard-lockscreen/ I decided to see if this works in KDE. While it seems with the greeter, there is no way to see the contents in plain text, the password field does get filled with the contents of the clipboard. With this I guess, could allow someone to unlock the screen in the unlikely and ill advisable scenario that the user copies their password, then locks the screen This is under X11, I have not tested Wayland yet.
Git commit cae1e82fc94f23f735ae3c189030505a95810cb5 by Martin Gräßlin. Committed on 17/02/2017 at 15:23. Pushed by graesslin into branch 'master'. [greeter] Clear clipboard on show Summary: As we have a feature to show the password it would be possible for an unauthorized user to get access to the clipboard. To prevent this, the clipboard gets cleared when we have the window shown. This is late enough on Wayland to be able to clear the clipboard. FIXED-IN: 5.10 Test Plan: On Wayland, paste is no longer possible. X11 is untested, there klipper might restore clipboard content.
