A Module is of a certain Type.

A Subject is an authenticated resource owner. Each time someone logs in, a new subject is created. The Subject MAY be linked to an user via a Link. The Link holds a user identifier and the static subject identifier.

The reason for this is to allow different subjects to exist as the same time. For example the same Facebook user from the same

The authenticated subject identifier is based upon the first subject in the chain

Identity has one or more subjects!

During the Chain with have a living subject. Each module may emit a living subject.

After the authentication chain has been completed, the subject is saved. The saved subject is authenticated.

An AuthResponse can be generated from a State. The State contains all state details. The AuthReponse contains informative information on how to meet the state requirements.

If no authentication level is specified, AuthChain enforces the user to complete all modules he faces.

For example, even if a second-factor is not required by the application, the user MUST still complete it, if he has configured this.
