Analyze password entropy, crack time, and check against known data breaches. Your password never leaves the browser.
All password analysis is performed locally in your browser. The breach check uses k-anonymity: only the first 5 characters of your password's SHA-1 hash are sent to Have I Been Pwned. The full hash never leaves your device.
