Is Jitsi insecure?

New user here. Went to Jitsi.org and clicked to start an online meeting.

It looks great that it’s easy, but entering a username of ‘Rob’ and on clicking enter, I was straight into someone else’s conference call. With video.

Is that what is supposed to happen?

Apparently someone else had named its room Rob. That’s why if you cannot come up with a unique room name, just hit join and there is a unique room name pre-generated for you, then use the link to send it to your friends to join you in that room.

Thank you for the explanation.

I was just surprised that it allowed it, but clearly the person using that room (Rob) had not set a password.

It would be good to have a password by default, I think.
