This Symfony-bundle integrates the Rollerworks PasswordStrengthValidator into your Symfony application.

The PasswordStrengthValidator provides various password strength validators for the Symfony Validator.

This bundle provides the same level of functionality as the PasswordStrengthBundle created by John Bafford. And is considered a replacement of the original bundle.


To install this package, add rollerworks/password-strength-bundle to your composer.json:

$ php composer.phar require rollerworks/password-strength-bundle

Now, Composer will automatically download all required files, and install them for you.

Step2: Enable the bundle

Note: This step is not required for Symfony Flex.

Enable the bundle in the kernel:


// in AppKernel::registerBundles()
$bundles = [
    // ...
    new Rollerworks\Bundle\PasswordStrengthBundle\RollerworksPasswordStrengthBundle(),
    // ...


You need at least PHP 5.6 or PHP 7.0, mbstring is recommended but not required. For the provided blacklist providers you may need SQLite3 or a PDO compatible driver.

Congratulations! You're ready!
