Frequently Asked Questions
How long to crack 8 characters?
Lowercase-only at 10B guesses/sec: hours. Add uppercase, digits, symbols (95 charset): same length jumps to years. Length beats complexity — 12 chars dwarfs 8 every time.
Does this help attackers?
No — the math is textbook combinatorics defenders already use. It justifies passphrases and MFA to skeptics with numbers.
Is my input uploaded?
No — estimation runs locally in your browser. Passwords never leave your device — never enter real ones anywhere.
