Password Security Guide
How long should my password be? ▼
Security experts recommend at least 12 characters for general use, 16+ for important accounts, and 20+ for critical systems. Longer passwords are exponentially harder to crack — a 20-character password is millions of times stronger than a 12-character one.
Are the passwords generated here truly random? ▼
Yes! We use the browser's built-in crypto.getRandomValues() — the same cryptographically secure random number generator used by banks and security software. It's far more random than Math.random().
Is it safe to use an online password generator? ▼
With CodeCanvas, yes — absolutely. All generation happens 100% in your browser. The passwords are never sent to our server, never logged, and never stored. You can even use this tool offline after the page loads.
What makes a password strong? ▼
A strong password has: (1) Length of 16+ characters, (2) Mix of uppercase, lowercase, numbers and symbols, (3) No dictionary words, (4) No personal information, (5) Unique — not reused across sites. Use a password manager to store complex passwords securely.
