Breached Password Checker
Check if your password has been exposed in a known data breach. This tool securely checks your password against the "Have I Been Pwned?" database without ever sending your password anywhere.
Type a password above to see if it has appeared in a data breach.
How it works: Your password is never sent to any server. It is securely hashed in your browser, and only the first 5 characters of the hash are sent to the Pwned Passwords API. This process, called k-Anonymity, allows you to check for breaches while keeping your password private.
