Where I work just switching into a TTY would be enough to keep anyone out.

Kscreenlocker because it came as default and I made it look identical to sddm

I use i3 lock, scrot and imagemagik to make my lock screen a blurred version of my actual screen

Whatever comes with GNOME/gdm.

None.

Why? Erm, living by myself I don’t need to lock myself out ;)

slock. i don’t really use anything else from the suckless people, but i like how minimal slock is

Swaylock, but the one with effects. Using it to leave a blurred picture of the current screen without anything readable. Works well for two years now, is wayland only

Whatever one comes with Manjaro KDE.

Because I don’t really care.

None currently, because I live with my family and if I wanted to hide anything from them (which I don’t), I could just switch to a tty, or log out. Most of my work is done in VSCodium or Vivaldi, which save their sessions, although I have considered doing one just in case.

I’ve always used i3lock. I also made a script to randomly select a background. Plus the login password circle thing looks cool. Would definitely recommend.

Waylock, because it keeps sway locked even if the screen locker crashes.

By screen locker, what do you mean exactly? Do you mean a setting that automatically locks your screen after a preset amount of time? If so, yes I do.

SDDM 0.20 Wayland mode is awesome!

Swaylock with Hyprland, I just run it from a terminal whenever I want to lock my screen but I guess I should make a keyboard shortcut for it.

I thought that slock was too complicated so I wrote a tiny one for myself in Go using xgb. Less than 100 lines and pretty straightforward but it makes some assumption about my personal setup so not public.
