Duplicate Password Checker

This module scans your PrestaShop store's customer and employee accounts to detect users who share identical passwords — a common security vulnerability that increases the risk of credential-based account compromise. When duplicate passwords are identified, the module can automatically send notification emails to the affected users, prompting them to update their credentials.

• Lists all customers and employees whose password hashes match another account in a single consolidated view
• Sends password change notification emails to affected customers and employees
• Compatible with multi-store setups

This module is useful for store administrators who want to proactively identify password reuse across their user base. Installation follows the native PrestaShop process and does not require any override files.
