Goal
Spoiler Alert: User passwords never leave your server, not even in hashed form.
Although reusing passwords is solely users' fault but when evil attackers brute forced users' passwords, and stole all their personal information or spent users' hard earn money through your site. Those lazy users blame you, the site owner/developer.
When processing requests to establish and change memorized secrets, verifiers SHALL compare the prospective secrets against a list that contains values known to be commonly-used, expected, or compromised. For example,...
- Passwords obtained from previous breach corpuses
This plugin's solely purpose is to disallow WordPress and WooCommerce users reusing passwords listed in Have I Been Pwned database.
Explain It Like I'm Five
- Troy Hunt, a well-kown security expert, collected 6,493,641,194 (and counting) pwned passwords from previous security breaches

- Whenever WordPress / WooCommerce users attempt to change their passwords, this plugin hashes the user password
- Take the first 5 characters from the hash
- Ask haveibeenpwned.com for all pwned passwords with the same first 5 hash characters
- Check how many times the user password appears on the have I been pwned database
- Disallow the password change if it has been pwned

Paranoia users should check the plugin implementation.
What to do if I don't trust haveibeenpwned.com?
Troy Hunt is a well-kown security expert. You should trust him more than me (the plugin author). Anyways, you can replace the default API client with yours:
This plugin uses league/container. Learn more from its documents.
What to do if I don't trust the plugin author?
Good question! You shouldn't blindly trust any random security guide/plugin from the scary internet - including this one!
Review the plugin implementation.
I have installed this plugin. Does it mean my WordPress site is unhackable?
No website is unhackable.
To have a secure WordPress site, you have to keep all these up-to-date:
- WordPress core
- PHP
- this plugin
- all other WordPress themes and plugins
- everything on the server
- other security practices
- your mindset
Strongly recommended:
- WP Password Argon Two - Securely store WordPress user passwords in database with Argon2i hashing and SHA-512 HMAC using PHP's native functions
- WP Cloudflare Guard - Connecting WordPress with Cloudflare firewall, protect your WordPress site at DNS level. Automatically create firewall rules to block dangerous IPs
- Two-Factor
- wp-password-bcrypt
Can strong passwords been pwned?
Yes. Example:

For testing only, use at your own risk!
Will you add support for older PHP versions?
Never! This plugin will only works on actively supported PHP versions.
Don't use it on end of life or security fixes only PHP versions.
Note: Current version supports PHP 7.0 because wordpress.org svn pre-commit hook rejects PHP 7.1+ syntax. However, you should not use PHP 7.0 because it has reached end of life since 10 January 2019.
