Check how strong your password is. Get detailed analysis of entropy, crack time estimation, and suggestions to improve security.
Yes! All analysis happens entirely in your browser. Your password is never sent to any server or stored anywhere.
A strong password is at least 12 characters long, uses a mix of uppercase, lowercase, numbers, and symbols, and avoids common words or patterns.
Crack time is estimated based on password entropy (randomness) and assumes an attacker making 10 billion guesses per second with modern hardware.
