This subclass of Provider defines methods that allow users to "log in" before using the provider's services. An implementation of the login( ) method should use the supplied javax.security.auth.callback.CallbackHandler class to request the user 's password or other authentication credentials. If no callback handler is passed to login( ) , it should use the one registered with setCallbackHandler( ) or a default.
