**Note: This plugin sends e-mail address (and optionally SHA1 hashed passwords) to an external API, at https://haveibeenpwned.com **
This plugin is meant to provide a service to your site members by doing the following:
- On user registration, check the haveibeenpwned API to see if their e-mail has been in any known breaches
- Stores (in user_meta) any breaches found, and if the user has been notified (by your site)
- If welcome e-mails are enabled, adds a section sharing information about the breaches, and the suggestion to use a strong password with a link to help. If not, it also lets them know they are clean.
- Optional (Disabled by default): Enable password checking against the API’s list of known passwords on password reset / new user password set. This only triggers if the user also has had their e-mail leaked in a known breach, and e-mails the user with additional information.
Planned for future updates:
- (Toggleable) Method of checking existing users and notifying them.
- (Toggleable) Method to periodically check all users that haven’t had a breach, and notify them if that changes.
- (Toggleable) Method to add admin notifications of new breaches discovered by HaveIBeenPwned.com

- What do I need for this plugin to run?
You must have at LEAST WordPress 4.9.0 or higher, as it uses the wp_new_user_notification_email filter.
- Is checking passwords secure?
Passwords are first hashed on-site using sha1, and then sent over https. This is as secure as using the haveibeenpwned password service yourself. This is turned OFF by default, but may be turned on on the settings page.
