+Import this optional dependency, if you want enable a security layer and allow the access to the REST API and to the UI only to authenticated users.  
+The authentication model of Quartz Manager is based on [JWT](https://jwt.io/).
+
+If you're going to import Quartz Manager in a project with an existing configuration of Spring Security, consider the following:
+- Quartz Manager Security relies on Spring Security upon a dedicated *HTTP Spring Security Chain* applied to the path `/quartz-manager`. So it doesn't interfere with your existing security setup
+- Quartz Manager Security keeps simple the authentication, adopting the InMemory Model. You have to define the users (in terms of username/credentials passed via `application.properties`) can access to Quartz Manager.
+-By default, the UI attaches the JWT Token to each request in the authorization header in the "Bearer" format.
+
+(To be checked: cookies with no presence of quartz-manager-security + no ADMIN role)
