Note: This demonstration uses numeric-only codes (0-9). Real passwords using letters (uppercase and lowercase), numbers, and symbols have exponentially more possible combinations. A 4-character password using all available characters has over 7 million combinations, while an 8-character password has over 200 trillion. The attack speeds shown range from simple desktop attempts to sophisticated distributed attacks.
