An account is what a user of Varnish Controller must have. There are two types of accounts:
The system administrator has by default full access to all resources and can view everything via the API. It also
has more access than a regular user in terms of
tags handling (see permissions).
A regular user is a user assigned to at least one organization in order to be able to log in to the system.
An organization administrator is not a specific type of user account, rather a regular user given full permissions to an organization.
The first user of an organization is given full permissions. It is only the system administrator that can assign the first user of an organization.
See authorization examples for examples of account management.
