 ## Changes to the Login Process
 The following two-factor authentication routes will be added automatically:
 ```php
-$router->get('/auth/token', 'App\Http\Controllers\Auth\TwoFactorAuthController@showTwoFactorForm')->name('auth.token');
-$router->post('/auth/token', 'App\Http\Controllers\Auth\TwoFactorAuthController@verifyToken');
+$router->group([
+    'middleware' => ['web', 'guest'],
+    'namespace' => 'App\Http\Controllers\Auth',
+], function () use ($router) {
+    $router->get('/auth/token', 'TwoFactorAuthController@showTwoFactorForm')->name('auth.token');
+    $router->post('/auth/token', 'TwoFactorAuthController@verifyToken');
+});
 ```
 The first route is the route the user will be redirected to once the two-factor authentication process has been initiated. The second route is used to verify the two-factor authentication token that is to be entered by the user. The `showTwoFactorForm` controller method does exactly what it says. There do exist cases where you might want to respond differently however. For instance, instead of loading a view you might just want to return a `json` response. In that case you can simply overwrite `showTwoFactorForm` in the `TwoFactorAuthController` to be discussed below.

-The body of the second function can be left empty if you do not want to send a two-factor authentication token automatically after a successful login attempt. Instead, you might want the user to instantiate this process from the form him/herself. In that case you would have to add the required route(s) and controller method(s) yourself. The best place for this would be the `TwoFactorAuthController` to be discussed next.
