+Authentication Success and Failure Events
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When a provider authenticates the user, a ``security.authentication.success``
+event is dispatched. But beware - this event will fire, for example, on *every*
+request if you have session-based authentication. See ``security.interactive_login``
+below if you need to do something when a user *actually* logs in.
+
+When a provider attempts authentication but fails (i.e. throws an ``AuthenticationException``),
+a ``security.authentication.failure`` event is dispatched. You could listen on
+the ``security.authentication.failure`` event, for example, in order to log
+failed login attempts.
+
+Security Events
+~~~~~~~~~~~~~~~
+
+The ``security.interactive_login`` event is triggered after a user has actively
+logged into your website.  It is important to distinguish this action from
+non-interactive authentication methods, such as:
+
+* authentication based on a "remember me" cookie.
+* authentication based on your session.
+* authentication using a HTTP basic or HTTP digest header.
+
+You could listen on the ``security.interactive_login`` event, for example, in
+order to give your user a welcome flash message every time they log in.
+
+The ``security.switch_user`` event is triggered every time you activate
+the ``switch_user`` firewall listener.
+
