*SecurityServiceProvider*::

    $app->register(new Silex\Provider\SecurityServiceProvider());
    $app->register(new Silex\Provider\RememberMeServiceProvider());

    $app['security.firewalls'] = array(
        'my-firewall' => array(
            'pattern'     => '^/secure$',
            'form'        => true,
            'logout'      => true,
            'remember_me' => array(
                'key'                => 'Choose_A_Unique_Random_Key',
                'always_remember_me' => true,
                /* Other options */
