Zxcvbn Symfony Bundle

A bundle to integrate zxcvbn-php with your symfony app. Supports localization and custom matchers.

Installation

composer require createnl/zxcvbn-bundle

Basic Usage

use Createnl\ZxcvbnBundle\ZxcvbnFactoryInterface;

class PasswordController
{
    public function updatePassword(string $password, ZxcvbnFactoryInterface $zxcvbnFactory)
    {
        $userData = [
          'Marco',
          '[email protected]'
        ];

        $zxcvbn = $zxcvbnFactory->createZxcvbn();

        $weak = $zxcvbn->passwordStrength($password, $userData);
        echo $weak['score']; // will print 0
        
        $strong = $zxcvbn->passwordStrength('correct horse battery staple');
        echo $strong['score']; // will print 4

        echo $weak['feedback']['warning']; // will print user-facing feedback on the password, set only when score <= 2
        echo $weak['feedback']['suggestions']; // may contain user-facing suggestions to improve the score
    }
}

Localization

This package supports the localization of warning and suggestion messages. Checks on common passwords, words and (family) names are only in English (US). But you can tag your own matcher to extend to your needs.

Supported languages:

• Dutch 🇳🇱
• English 🇺🇸

Extending matchers
