The fields in the user registration form reuse properties that you define as entity details for Person entities, such as FirstName and LastName. You can add more properties to further customize the registration process, for example, by adding security questions.
Follow the procedure for adding properties to Person entities in Extending the entity details form.
Include the property as a registration form field by adding the new property to the CaptureInfo section of the PegaPS-Data-Registration class.
