Adding authentification to room creation

You probably want to restrict the creation of new rooms to some users, but still allow everyone with the link to join a room. For this we can configure jicofo:

You might also want to take a look at the official docs on this topic.

First edit the /etc/prosody/conf.avail/jitsi.yourdomain.example.cfg.lua. In the main VirtualHost, replace anonymous authentication with internal_plain. Next up create a new VirtualHost below for e.g. guest.jitsi.yourdomain.example with anonymous authentication.

Afterwards the file should look similar to this:

VirtualHost "jitsi.yourdomain.example"
        -- enabled = false -- Remove this line to enable this host
        authentication = "internal_plain"
        -- Properties below are modified by jitsi-meet-tokens package config
        -- and authentication above is switched to "token"
        --app_id="example_app_id"
        --app_secret="example_app_secret"
        -- Assign this host a certificate for TLS, otherwise it would use the one
        -- set in the global section (if any).
        -- Note that old-style SSL on port 5223 only supports one certificate, and will always
        -- use the global one.
        ssl = {
                key = "/etc/prosody/certs/jitsi.yourdomain.example.key";
                certificate = "/etc/prosody/certs/jitsi.yourdomain.example.crt";
        }
        -- we need bosh
        modules_enabled = {
            "bosh";
            "pubsub";
            "ping"; -- Enable mod_ping
        }

        c2s_require_encryption = false

VirtualHost "guest.jitsi.yourdomain.example"
    authentication = "anonymous"
    c2s_require_encryption = false

---

Next up, you have to edit the config.js at /etc/jitsi/meet/jitsi.yourdomain.example-config.js.

It should already have a line for anonymousdomain which you only need to uncomment and specify the domain of the new VirtualHost.

var config = {
    hosts: {
        // XMPP domain.
        domain: 'jitsi.yourdomain.example',

        // When using authentication, domain for guest users.
        anonymousdomain: 'guest.jitsi.yourdomain.example',
      [...]
    }
}

---

Now we need to enable the authentification in jicofo. For this we create /etc/jitsi/jicofo/sip-communicator.properties and set it to

org.jitsi.jicofo.auth.URL=XMPP:jitsi.yourdomain.example

---

After every config is set, we can restart jicofo and prosody

sudo systemctl restart prosody.service
sudo systemctl restart jicofo.service

---

And lastly we can create users using prosodyctl:

prosodyctl register <username> jitsi-meet.example.com <password>

---

Now when you create a new room, you can click on I am the host and enter the username/passwort. Every following user will be able to join directly.

Using existing user databases

As jitsi is using Prosody for this, you can use e.g. IMAP, LDAP, Wordpress and many more for authentication.

But if you just want to limit the instance to the people you know, a single shared user account as set up above might be enough.
