The Roles view in the Auth.it Dashboard allows you to create global roles:

Auth.it supports two types of roles:

To assign roles to a user, go to the Users view, select a user profile, and open the Roles tab. From there, you can assign roles to the user by clicking Assign Role.

Including the list of global roles in the token allows your application to make authorization decisions based on role membership.
