Gopass Bridge allows searching and inserting login credentials from the gopass password manager.
Gopass (https://www.gopass.pw) is the awesome command line password manager. This plugin enables input of login credentials from gopass. To access gopass, a native app has to be configured in the browser in addition to this plugin. The native app is a wrapper that calls gopass with the jsonapi parameter to communicate via stdin/stdout. For details on configuring native messaging, see the plugin development page on https://github.com/gopasspw/gopassbridge
