The Galene family has got a new member: The Wordpress plugin 'Galène video conferencing manager'.

This is not a full client (like Pyrite, for example) but an administration frontend with the following features:

Create group files (.json) via SFTP, filesystem, or import/export
Authentication via JWT key
Set up rooms that can be accessed via an access code
Set up rooms that can be accessed via username/password
Internal user management
Authentication possible via Wordpress roles
Generate links for the respective access to the rooms.

You can find it on Github https://github.com/printpagestopdf/galene-manager

Or in the WordPress plugin directory https://wordpress.org/plugins/manager-for-galene-videoconference/
