Frequently Asked Questions
Are these passwords truly random?
Yes. This tool uses the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random numbers, the same standard used by password managers.
What makes a password strong?
A strong password is at least 12-16 characters long and uses a mix of uppercase, lowercase, numbers, and symbols. Longer passwords are exponentially harder to crack.
Are my passwords stored anywhere?
No. Passwords are generated entirely in your browser and are never sent to any server. Once you close the page, they're gone unless you copied them.
How is crack time estimated?
The crack time is estimated assuming a brute-force attack at 10 billion guesses per second (modern GPU cluster). Actual time depends on the attack method and hardware used.
