Frequently Asked Questions

Is this password generator safe to use?
Yes. All passwords are generated locally in your browser using JavaScript's crypto.getRandomValues() — a cryptographically secure random function. No password is ever sent to any server. The tool has no network calls and works completely offline once the page is loaded.
How long should a strong password be?
Security experts recommend at least 12–16 characters for regular accounts and 20+ characters for banking, email, or admin accounts. A 16-character password with all four character types would take billions of years to crack by brute force with current technology. Length matters more than complexity.
Should I use the same password on multiple sites?
Never reuse passwords. If one site gets hacked and your password leaks, attackers will try the same password on your email, bank, and other accounts — this is called a "credential stuffing" attack. Use a unique strong password for each account and store them in a password manager so you never need to remember them.
