🛡 Password Leak Check
Enter your password to check if it has been exposed in known data breaches. Your password is never sent — only a hash prefix is used to ensure full privacy.
How Does It Work?
We use the k-anonymity model developed by Troy Hunt (creator of HaveIBeenPwned). Only the first 5 characters of your password's SHA-1 hash are sent — never the full password.
This guarantees complete privacy. Even if you're checking a sensitive password, it will never be revealed or stored.
