Abstract: Authentication of a user of an OAuth client by an OAuth authorization server, comprising exposing an authentication state machine, where the states of the state machine are hypermedia-based representations of login resources, and transitions between states are represented by hypermedia links, wherein the authentication state machine is exposed to the client by an API adhering to the principles of REpresentational State Transfer (REST). When the final state of the state machine has been reached, a secondary access token is issued to the client, thereby authenticating the user, wherein hypermedia representations which are sent to the client are encoded so as to be readily parsable by the client.
