Password checker
See how strong a password is and whether it appears in known data breaches.
Information only: these tools show what they find and can be wrong. They can't tell you that a link, QR code or password can be trusted.
Strength:
The strength estimate runs on your device using zxcvbn-ts.
Has it leaked?
The password never leaves your device. The leak check sends only the first 5 characters of its SHA-1 hash to Have I Been Pwned, not the password or its full hash.
Leak data: Pwned Passwords by Have I Been Pwned. Not affiliated with or endorsed by Have I Been Pwned.
Tips
- Use a different password for every account.
- Long passphrases of several random words are strong and easy to remember.
- A password manager can create and remember passwords for you.
