A strong password is at least 12 characters long and includes a mix of uppercase and lowercase letters, numbers, and special characters. Avoid using names, dates, or common words.
We estimate strength based on password length and variety of character types selected (uppercase, lowercase, numbers, symbols), and display a visual score and feedback message.
Yes, all passwords are generated locally in your browser using cryptographically secure random number generation. Nothing is stored or transmitted to our servers.
Short or predictable passwords are highly vulnerable to brute-force and dictionary attacks. The longer and more complex your password, the harder it is to crack, sometimes taking years or centuries with current technology.
