How to prevent random users to use my Jitsi installation

Beginners question:
Just installed Jitsi on my Ubuntu server. Configured NAT on my router. Jitsi is working fine!
But now i realize that everybody on the internet who knows my Jitsi URL can use it. I want to prevent that. Any suggestions?

Check this out : https://github.com/jitsi/jicofo#secure-domain

Thanks Toofunal! I will give it a try :slight_smile:

I took me some time (nog very used to edit files with nano) but i think i eddited the files as in the artikel.
When i visit my Jitsi page it turns black.
Any suggestions?

Double-check you made the edits correctly.

Did you restart your server after making the changes?

Restart done.
Same result.
Maybe i made a mistake in a edit?
Not shure where to put this line (-Dorg.jitsi.jicofo.auth.URL=XMPP:jitsi-meet.example.com)

This by the following intruction. Of course i replaced the FQDN with my own)

When running Jicofo specify your main domain in additional configuration property. Jicofo will accept conference allocation requests only from authenticated domain.

-Dorg.jitsi.jicofo.auth.URL=XMPP:jitsi-meet.example.com

If you have Jicofo installed from the Debian package this should go directly on a new line in the /etc/jitsi/jicofo/sip-communicator.properties file:

org.jitsi.jicofo.auth.URL=XMPP:jitsi-meet.example.com

Here:

/etc/jitsi/jicofo/sip-communicator.properties

At the end i followed the instructions on https://youtu.be/IQRwtUamHQU
This worked for me!
Not exactly the same as https://github.com/jitsi/jicofo#secure-domain
But it worked for me!
Thank you all.
cheers!
