You do not need anyone's password and nobody on the team signs in to anything. Your IT admin does one thing on their side — about two minutes — and then you choose which inboxes Monty uses from a list. Here is the whole flow from your side.
If the admin has a question about what they are granting, the page they land on answers it, and so does the article for their provider below. They do not need a Monty account.
