Overview

An authorization is a record that a User has been authorized somehow. Other models in the system can use different kind of authorizations to allow a user to perform actions.

To create an authorization for a user we need to use an AuthorizationHandler that validates the user against a set of rules. An example could be a handler that validates a user email against an API and depending on the response it allows the creation of the authorization or not.
