EmpowerID allows you to control and track access to applications not inventoried by EmpowerID through the use of a special type of account store internal to EmpowerID, known as a "tracking-only" account store. Each tracking-only account store has a one-to-one relationship with a specific application that is established at the time the application is created in EmpowerID.
Now that the account store is created, you can use it when creating a related tracking-only application.
