No, but you can force every user that wants to make a room to be registered in prosody with “Jitsi Secure Website” configuration… doing this only moderators with a username and password could open a new room and others could only wait the moderators in the room
Till Jitsi doesn’t come up with some post or get based authentication.
You may want to look at “xmpp_username_override” , “xmpp_password_override”
local Storage key value pair for authentication.
You may just create a page where you take username and password and set it to window.localStorage
