How it works

Password strength grows exponentially with length. An 8-character password with 94 printable ASCII characters has 94⁸ ≈ 6 quadrillion combinations—crackable in hours with modern GPUs. A 16-character random password has 94¹⁶ combinations—effectively uncrackable. Use a password manager to store unique passwords for every site. Passphrases (4–5 random words) are memorable and strong.
