About Know Your Password

Know Your Password is an independent project focused on helping people create and test stronger passwords without giving up privacy or speed.

All password analysis starts in your browser. We use the open‑source zxcvbn strength estimator and the Have I Been Pwned Pwned Passwords API via k‑anonymity so your full passwords are never sent to our server.

The tools on this site are designed to be fast, minimal, and easy to understand, so anyone can quickly see if a password is weak, reused, or appears in known breaches, and then upgrade to a safer password or passphrase.

Our goal is to make good password hygiene easier: test your password, generate a stronger one, and store it in a reputable password manager with multi‑factor authentication enabled.
