The SYSTEM provides an easy-to-implement way to have centralized authentification for multiple users against multiple services. It is similar in this respect to the OpenID and OpenID Connect projects, but unlike those does not support federation across multiple identity providers at a benefit to ease of implementation.
Service using the SYSTEM for authentication need to be registered with it first (which can be done by a normal user) and provide an endpoint to a specified Callback interface (See PROTOCOL.txt for detailed information).
Users are able to store additional information about their accounts (attributes) with the system, which may be used by requesting services.
