warning users about insecure passwords

laravel pwned passwords validator

This small guide expects you to have my pwned passwords validator for laravel 5.6. It’s painless to install and set up:

$ composer require acodeninja/laravel-pwned-passwords-validator

Once installed, Laravel’s package discovery will take care of loading the package for use in your application. Read more about using the validator .

checking passwords and warning users on login

To check if a password is secure each time a user logs in you can use the validator. To do this, you use the validator and redirect with errors if the login password fails to pass.

Simply put, add the following to your application’s login controller, in a default application this is at app/Http/Controllers/Auth/LoginController.php.

 * @param Request $request
 * @param User $user
 * @return $this|\Illuminate\Http\RedirectResponse
public function authenticated(Request $request, User $user)
    $validator = Validator::make($request->all(), [
        'password' => 'required|pwned_password_strict',

    $redirect = redirect()->intended($this->redirectPath());

    return $validator->fails() ?
    	$redirect->withErrors($validator->errors()) :

You can then display the errors as normal on the page your application redirects to, normally this would be resources/views/home.blade.php.

@if ($errors->any())
    <div class="alert alert-danger">         
        @foreach ($errors->all() as $error)
            <li>{{ $error }}</li>

Or you can make it look a little nicer and display it above other messages with something like the following.

@if ($errors->has('password'))     
    <div class="alert alert-danger">         
        {{ $errors->first('password') }}
