You can manage team members and assign roles via the Team page (select the Team menu option from the Dashboard sidebar).

The following user roles can be assigned to a user / team member:

This role has full Dashboard permissions and is identical to the Team Owner. Team Administrators can create / remove users and assign roles so use with caution! 

This role has full Dashboard permissions but without the ability to create and edit Dashboard users / team members and without access to billing-related information. 

This role is a subset of the Websites Administrator role and restricts user access to specific website(s). The Website Manager can perform all operations except cloning and removing websites.

This role enables Dashboard users to access and edit billing-related information only, as well as download and pay invoices.
