Implementing SSO

To authenticate a user with Livefyre through a flow not triggered by a Livefyre App, Livefyre recommends that you implement the forEachAuthentication method on your AuthDelegate object.

This will be invoked when the authDelegate is passed to auth.delegate, and will be passed an authenticate function that can be passed multiple times. This method provides an inversion of control for authentication events so that your AuthDelegateobject can be self-contained without requiring a global reference to auth.

authDelegate.forEachAuthentication = function (authenticate) {
 window.addEventListener('userAuthenticated', function(data) {
  authenticate({livefyre: data.token});
 });
}

Livefyre relies on user tokens to coordinate authentication. As a result, this token must be returned by your identity service to authenticate a user with Livefyre. To learn how to create a Livefyre user token, please see Building a User Authentication Token.

NOTE

After a successful login, auth will create a session for the user, and will try to load a user’s session upon page refresh and reload. auth.logout() will clear this session. This means that it is not necessary to manage a user’s session independently of authorization.
