How can I add captcha/Google-reCaptcha to user auth login? there is only validation for register that I can modify, how can I modify validation for login?

my problem is not how to add recaptcha, my problem is how to add recaptcha validattion to login validation rules.

Here's how i figured it out, for anyone else that also has this problem (using http://github.com/greggilbert/recaptcha):

Copy the validateLogin function from vendor\laravel\framework\src\Illuminate\Foundation\Auth\AuthenticatesUsers.php to app\http\Controllers\Auth\AuthController.php and just add the line to the array. You end up with this:

    /**
 * Handle a login request to the application.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
protected function validateLogin(\Illuminate\Http\Request $request)
{
    $this->validate($request, [
        $this->loginUsername() => 'required', 'password' => 'required','g-recaptcha-response' => 'required|recaptcha',
    ]);
}

That's it, captcha works now on login form. (You should ofcourse also add {!! Recaptcha::render() !!} in the login view)

That's how I figure it out, I copied postLogin method from vendor/laravel/framework/src/Illuminate/Foundation/Auth/AuthenicatesUsers.php and edit it like bellow:

/**
 * Handle a login request to the application.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function postLogin(\Illuminate\Http\Request $request)
{
    $this->validate($request, [
        $this->loginUsername() => 'required', 
        'password' => 'required',
        'g-recaptcha-response' => 'required|recaptcha'
    ]);

    // If the class is using the ThrottlesLogins trait, we can automatically throttle
    // the login attempts for this application. We'll key this by the username and
    // the IP address of the client making these requests into this application.
    $throttles = $this->isUsingThrottlesLoginsTrait();

    if ($throttles && $this->hasTooManyLoginAttempts($request)) {
        return $this->sendLockoutResponse($request);
    }

    $credentials = $this->getCredentials($request);

    if (\Auth::attempt($credentials, $request->has('remember'))) {
        return $this->handleUserWasAuthenticated($request, $throttles);
    }

    // If the login attempt was unsuccessful we will increment the number of attempts
    // to login and redirect the user back to the login form. Of course, when this
    // user surpasses their maximum number of attempts they will get locked out.
    if ($throttles) {
        $this->incrementLoginAttempts($request);
    }

    return redirect($this->loginPath())
        ->withInput($request->only($this->loginUsername(), 'remember'))
        ->withErrors([
            $this->loginUsername() => $this->getFailedLoginMessage(),
        ]);
}

then I changed validation rules of login and add 'g-recaptcha-response' => 'required|recaptcha' in order to use Google recaptcha (https://github.com/greggilbert/recaptcha)
