Leak Checker

Instantly check if your password has appeared in a known data breach.

Is this safe?

Yes. We use a method called "k-Anonymity". Your password is never sent to us or any third party.

We only send the first 5 characters of a secure hash of your password. The actual check happens right here in your browser.

What to do if leaked?

Change your password immediately on all accounts where you use it.

Use a unique password for every service and enable Two-Factor Authentication (2FA).
