Password Leak Checker
Check if your password has been exposed in data breaches. Enter your password below to check if it has been compromised. Your password is never sent to our servers – we use secure k-anonymity model.
In today’s digital landscape, password security is more critical than ever. With data breaches becoming increasingly common, understanding how to protect your passwords and regularly checking their security status has become essential for maintaining digital safety.

Frequently Asked Questions
Q: How often should I check my passwords?
A: It’s recommended to check your passwords at least monthly and immediately after any reported data breaches.
Q: Is my password sent to any servers during the check?
A: No, we use a k-anonymity model where only a partial hash is sent, ensuring your password remains private.
Q: What should I do if my password is compromised?
A: Immediately change the compromised password and any similar passwords used across different accounts.
Q: How secure is the checking process?
A: The process uses industry-standard SHA-1 hashing and secure API connections, with all processing done locally in your browser.
Q: Can I trust the results?
A: Yes, our tool uses data from verified breach databases and implements secure checking methods to provide accurate results.
