Give you access to your bitwarden passwords in Krunner, by writing "pass" and a search string.

The Krunner connection is to bwcli, the bitwarden command line client, https://bitwarden.com/help/article/cli/ (get it here https://bitwarden.com/download/).
The searches are a bit slow due bwcli.

See https://github.com/martininsulander/KrunnerBitwarden for more info.

Neither Bitwarden, nor Kde currently supports the dbus-protocol secretservice, so this is the next best.
