This is a Drupal 8 module that adds a PasswordStrength plugin to the D8 Password Policy module. Implemented from https://github.com/bjeavons/zxcvbn-php

After developing this module, I was informed about the following module: https://www.drupal.org/project/password_strength. This module is basically a D8 version of the module that now plugs into Password Policy.

Enable

• Download and enable the module
• Go to Password Policy's configuration page (/admin/config/security/password/settings)
• Click on the "Zxcvbn" tab
• Click "Add Policy" and define select the score you wish to use
• Go to the permissions page (/admin/people/permissions)
• Select which roles the Zxcvbn policy applies to
• Drink a beer

Configure

• Go to Password Policy Zxcvbn's configuration page (/admin/config/security/zxcvbn/settings)
• Turn on/off matchers
• Select your scorer and searcher

Architecture

• Base Zxcvbn class that bootstraps the code and the configured plugins
• Three plugin managers for full extensibility: Matcher, Scorer, and Searcher
