New at using Admin

[Wabigoon]

Im very new at this. We are a small board with new ZOOM access. Our secretary is 1000 miles from the chair. The secretary can initiate meetings and that is fine. The chair has been granted "admin" access to the Board zoom id. 

What we don't understand is what does that mean. Does the chair need to have the userid and password to the board zoom or can he login to his zoom free account and somehow have admin access to the baord paid zoom. 

What we need is either the secretary or the chair to be able to start zoom meetings under the board zoom account. The only option I see is sharing the account login credentials.  Also if the chair is an admin, how doe he do any admin activity unless he has the board zoom login?
