Who is ADMIN? How can I remove password request?

Hi @shirley6 welcome to the community! Could you please elaborate on 'participants needing a password'?

Second, I'd like to point out that Account Settings https://zoom.us/account/setting differ from Profile Settings https://zoom.us/profile/setting. That being said, I would first check the Account Settings for Requirements on Meeting passwords and configure to your liking there - then you should be able to configure at the profile settings level.

I have the same issue as Shirley.  I don't believe RN's reply addressed the issue. The setting Shirley refers to is greyed out and, as she says, labeled "only Admin can change". 

I am, as is Shirley, the owner of a pro account, but I cannot find out who is "Admin" for my account.  The support offered by Zoom seems mostly aimed at corporate accounts. Search as I can I find no information on how an owner can find the Admin. Intuitively it would seem the owner should be admin by default.
