Is it safe to check my password here?

Yes. We hash your password in your browser with SHA-1, then send only the first 5 characters of that hash to the Pwned Passwords range API. Your full password and full hash never leave your device.

Do you store my password?

No. Checking happens in your browser. We do not store passwords, hashes, or check history on our servers.

How is this different from Have I Been Pwned?

Have I Been Pwned is the gold standard for email breach lookups. Our tool focuses on private password checks plus practical safety guides. For email breach search, we recommend Have I Been Pwned directly.

Common questions

Is checking here safe?

Yes. The password is hashed in your browser. Only the first 5 characters of the SHA-1 hash are sent to the public Pwned Passwords range API. Your full password never hits our servers.

Why not check my email here?

Email breach search needs a large maintained corpus (like Have I Been Pwned). We won’t fake that database. Use Have I Been Pwned for email lookups — then come back for recovery playbooks.

What if my password was found?

Stop using it everywhere. Follow our breach response guide, enable 2FA, and rotate any reused logins.
