Room name insecure

Since i started using jitsi, i now get constantly a sing sayin:
room name insecure… etc.
What can i do other than constantly using other, longer names, in order thar no one can enter a conversation?

You can setup a password.

Thanks, i know, i always do. Is that sufficient?

a pass did not help here

That warning refers ONLY to the room name.
