User Roles

Administrator
Administrators can perform all actions in the account (manage groups and users) and have access to the whole application.

Manager
Managers have access to the whole application except the group and user management.

Viewer
Viewers have the same as managers but they cannot edit or manage the catalog.

Custom
You can set a custom role for any user. Just check/uncheck options needed (i.e here, this user will be only able to modify albums but won't have access to Analytics, Accounting, and User Admin sections).
