Elite AI Security

Is your password in a breach?

Free instant check against billions of compromised passwords. Your password never leaves your browser in full — we use HIBP k-anonymity (only a 5-character hash prefix is ever sent).

We SHA-1 your password locally, send only the first 5 hex characters to HaveIBeenPwned's range API, and match the rest here. The full password and full hash are never transmitted.
