🔓 Password Breach Check
🔒 100% private. Your password is never sent anywhere. We use k-anonymity — only the first 5 characters of a SHA-1 hash are sent to the HaveIBeenPwned API. Your actual password stays in your browser.
Enter a password and click Check to see if it appeared in any data breach
ℹ️ How Does This Work?

This tool checks your password against the HaveIBeenPwned database of over 10 billion breached passwords — without ever sending your actual password.

We use a technique called k-anonymity: your password is hashed with SHA-1, and only the first 5 characters of that hash are sent to the API. The API returns all hashes starting with those 5 characters, and we check locally if your password’s full hash is in the list. Your password never leaves your browser.

🎲 Passphrase Generator

Passphrases are easier to remember than random passwords and can be just as secure. “correct-horse-battery-staple” is stronger than “Tr0ub4dor&3”.

About This Tool

🔒 Is it safe to type my password here?
Yes. Everything runs in your browser. Your passwords are never sent to our servers — we cannot see them.
🔓 How does breach checking work?
We use k-anonymity with the HIBP API. Only a partial hash is sent — your actual password never leaves your browser.
🎲 Why use a passphrase?
4-5 random words are easier to remember and harder to crack than most complex passwords. “correct-horse-battery-staple” has ~51 bits of entropy.
🔄 Use a password manager
Generate a unique password for every site. Store them in Bitwarden (free) or 1Password. Never reuse passwords.
