This plugin let's you look up your KeepassXC entries and copy the passwords (and usernames as secondary action) to clipboard. It also comes with a small CLI tool to query that information manually.
- Python 3.6 or higher
- xsel or xclip installed
- KeepassXC installed and configured for Freedesktop.org Secret Service access (in both general and database settings)
As this is a python application communicating with krunner through D-Bus it needs to be running constantly, for this purpose the install script will place the executable at ~/.local/bin/krunner-keepassxc (you can run this for the CLI) and place a systemd unit file at ~/.config/systemd/user/ to control it. If you're not using systemd a KDE autostart script will be created instead.
