🔒 Password Strength Checker

Password Strength Checker

Our password strength checker evaluates your password against 10 security criteria including length, character diversity, and patterns to avoid. The entropy score measures how many bits of randomness the password contains — higher is better. A truly strong password should be at least 16 characters, use a mix of character types, avoid dictionary words, and have no repeated or sequential characters. Your password is analyzed entirely in your browser and never sent to any server.
