Jitsi Android app issue

If I creat a meeting with a password why it is allowed for others to remove the password and create their own password… In jitsi Android app… I mean if a host us creating a password then the same should be able to add or remove password not others… In my case I try to have a class with my students but some students change the password and it will not let others to join coz it will ask for new password… Plz resolve
