Specific Advice

🔒 Everything runs locally in your browser — your password is never uploaded, stored, or logged anywhere (close the tab and it's gone). Crack times are rough estimates for offline brute-force attacks, just to give you a sense of scale. The safest approach: use a password manager to generate random passwords of 16+ characters, unique for every site.
