We never see your password
Has your password been leaked?
Check any password against hundreds of millions of credentials exposed in data breaches. Your password never leaves your browser — only the first 5 characters of its hash are sent (k-anonymity).
Nothing is typed anywhere but your own browser. Data source: Have I Been Pwned (Pwned Passwords).
Private by design
We never see your password
Stays in your browser
The password is hashed locally with SHA-1. The plain password is never sent to us or anyone.
k-anonymity
Only the first 5 hex characters of the hash are queried — matching ~800 possible hashes, so your exact one is never revealed.
Nothing stored
No logging, no accounts, no history. Check as many as you like.
