There are three different Portal roles a user can be assigned to:
The Super Admin will serve as the primary contact of the Partner account and will receive notifications on Portal related updates and changes. This role has full access to all aspects of the Portal that are under the control of this partner and other related partner accounts.
There can be multiple Super Admin accounts for any partner company. The first person accessing the Portal from a given partner company is, by default, designated the Super Admin.
The Super Admin can invite other personnel as Super Admins, Admin and Standard portal users.
The Portal Admin role has the same ability to invite new users as the Super Admin role. This means an Admin user can invite additional users to access the Portal and designate the Tools role for the invited personnel. There can be multiple users with the Admin role, all of which will have the same ability to add or update Portal Users.
The one limitation is that Admins are unable to create or manage Super Admin accounts.
A Standard user can access the tools and other resources within the Portal, but does not have permission to add or update Portal users. There can be multiple users with the Standard role.
