Hi I have worked with zoom API and I would like to authenticate meeting so no one can join meeting only registered user but I have some questions for that 
1- does anyone have an account in a zoom that can join the meeting if he has the URL or only accounts which I registered on my account.
2- does each account I created will have a separate account with a dashboard as apart of my plan or free dashboard.
3-how can I invite-only some member of register account for meeting not all for example 10 out of 50 and so on
4- can I asked them to login with a username not email in case of join meeting
5- can the user login only from the web, not desktop and login for only not log in from multi-device for the same meeting
I use zoom API
thanks in advance
