Frequently Asked Questions
How secure is this password generator?
Uses the Web Crypto API (crypto.getRandomValues) for cryptographically secure randomness — the same standard used by browsers and operating systems.
Is my generated password stored anywhere?
No. Everything runs in your browser. No data is sent to any server.
What length should my password be?
Security experts recommend at least 16 characters with mixed character types for most accounts.
Should I use symbols in passwords?
Yes — symbols dramatically increase password entropy and resistance to brute-force attacks.
Can I generate multiple passwords at once?
Yes — use the "Generate 5 Passwords" option to get a batch of strong passwords instantly.
How often should I change passwords?
Change passwords when a service is breached. Use unique passwords for every account with a password manager.
