Free Online Strong Password Generator
Create cryptographically random passwords using your browser's Web Crypto API (crypto.getRandomValues). Adjust password length from 6 to 48 characters, toggle character sets (lowercase, uppercase, digits, symbols), and see real-time strength assessment. Generated passwords are never sent to or stored by any server — they exist only in your browser memory until you close the tab.
Strength: Fair
Common questions
Are these passwords generated securely?
Yes. Generation uses the browser's crypto.getRandomValues API, which is designed for cryptographic use — not Math.random, which is predictable and not suitable for security-sensitive randomness.
Are generated passwords stored anywhere?
No. Passwords are generated and displayed locally in your browser and are never sent to or logged by a server. When you close the tab, the password only exists if you've copied it.
How long should my password be?
Security experts recommend at least 12-16 characters with a mix of uppercase, lowercase, numbers, and symbols. For high-security accounts, use 20+ characters. Longer passwords are exponentially harder to crack.
