How long should a strong password be?

We recommend at least 16 characters with a mixture of uppercase, lowercase, numbers, and symbols for modern accounts.

Password Entropy & Security Best Practices

Password entropy measures how unpredictable a password is in bits. Longer passwords with diverse character sets drastically increase the number of guesses required for brute-force attacks, making cracking computationally unfeasible with modern hardware.

Security & Privacy Assurance

All passwords are generated locally inside your browser memory using `crypto.getRandomValues()`. Generated credentials are never saved, stored, or sent to any server.
