What is a principal?
Very simply, "principal" is just a fancy term for a user. For most applications, the terms "user" and "principal" are interchangeable because the application is only ever used by humans. However, Cerbos is not just for authorizing humans; it can also be used to authorize access from other applications, services, bots or anything you can think of. Therefore, we prefer to use the proper computer security term to make that clear.
