 An initial onboarding is required for authentication using application objects. Application and service principal are used interchangeably, but an application is like a class object while a service principal is like an instance of the class. You can learn more about this at [Application and service principal objects in Azure Active Directory](https://docs.microsoft.com/azure/active-directory/develop/app-objects-and-service-principals).
