Add 'Have I been pwned?' validator to Magento 2.

Magento 2 Have I Been Pwned Validator

This module adds a validator which checks if the submitted password is found in public databases using the Have I Been Pwned? service., _(*1)

Security

There are no security drawbacks, because there are no actual passwords being submitted over the internet. This is possible by hashing the password using the SHA-1 algorithm and request all hashes in the Have I been Pwned? databases starting with the first 5 characters of the password hash. This resultset contains a list of hashes and the amount of occurrences., _(*2)

This way the password stays inside the Magento process., _(*3)

Installation

composer require timpack/magento2-module-pwned-validator
bin/magento setup:upgrade

Configuration

You can configure the threshold of the validator, at which count of occurrences in the resultset the password should be considered insecure/invalid. This configuration can be found at:, _(*4)

Stores -> Configuration -> Customer -> Customer Configuration -> Pwned Validator -> Minimum amount of matches, _(*5)
