EDIT: Lol, it doesn’t actually work +___+ It is enabled in KeepassXC but it just doesn’t do anything. Welp.
Here’s a neat trick I just found out (with a hint from here):
In Wayland you can’t use KeepassXC’s very cool Auto-Type feature (it’s somehow Qt’s fault?) but if you installed it as a Flatpak you can go into KDE Settings, search for “Flatpak Permission Settings” and in the settings for KeepassXC under “Advanced” you can disable “Wayland Windowing System” to make it work. Nice!
I ran in to this problem in the past when I was testing Wayland out. Here is the solution that worked for me:
-platform xcbto the end of your keepassxc autostart entry, or start keepassxc with this tagged on the end from a terminal and it should work.This was months ago now though and I don't use Wayland regularly.
