Additional Password Policy validators for TYPO3 CMS

This extension for TYPO3 CMS contains additional Password Policy validators for usage in TYPO3 12+ projects. It also adds an event listener for the EnrichPasswordValidationContextDataEvent PSR-14 event, so the context data used for password validation is extended with the users email-address.
