Users and Roles
Security is based on the roles that are assigned to specific users. Roles do not have any structure or hierarchy by default, but it can be created. You can create a hierarchy based on users with a greater role being assigned all matching lesser roles.
There isn't a built-in restriction to the number of roles a user can have, so each user can be assigned many roles or none at all.
It's important to think about the different roles in your project and how they affect the security of your project. For instance, what level of access a particular area of a project needs may determine the functional type roles that you create, and the different users assigned to each role.
You can manage users and roles using either the Gateway interface, or using the User Management component inside the Designer or Client. This section shows how to manage users and roles using the Gateway interface under Config > Security > Users, Roles. Click on the manage users link for the User Source you want to administer.
