Password Breach Alert is a Devise extension that adds 1) server-side check of password strength before registration, using a list of common passwords, zxcvbn and haveibeenpwned; 2) a way to check users emails against recent verified security breaches, and implement different customized policies.

Generate a list of passwords from command line with options for length and complexity into a file of your choice.

You can setup the check when a password can be reused by a user. It lets you configure the last 'n' password can not be used by user when they change it.
