Which method is not part of user management in OutSystems?

Creating user roles at the time of login is not a standard method of user management in OutSystems. User roles are typically defined and configured within the application to manage permissions and access control effectively before users log in. This means that user roles should already be established and assigned to users, rather than being created during the login process.

In contrast, the other methods mentioned directly relate to established practices in user management. Programmatically creating users using Actions allows developers to add users efficiently through the application logic, while modifying user roles and deleting user accounts are also functions that are integral to managing user access and permissions within the platform. These capabilities allow proper administrative control over users and their roles but do not allow for the real-time creation of roles during user authentication events.
