How it keeps your password private

  1. 1

    Hashed on your computer

    Your password becomes a SHA-1 hash, e.g. 5BAA61E4C9B93F3F…, right in your browser.

  2. 2

    Only 5 characters leave

    Just 5BAA6 is sent to Have I Been Pwned. Hundreds of different passwords share that prefix.

  3. 3

    Matched on your computer

    The list that comes back is compared locally. Nobody, not even us, learns which password you checked.
