Secure Password Generator
Generate cryptographically strong random passwords using the Web Crypto API
About the Secure Password Generator
Our password generator uses the browser's built-in crypto.getRandomValues() API to generate truly random, cryptographically secure passwords. Unlike Math.random()-based generators, our tool produces passwords that are safe to use for accounts, APIs, and encryption keys.
What Makes a Strong Password?
- Length â Longer passwords are exponentially harder to crack. 16+ characters is recommended for most accounts; 32+ for highly sensitive systems.
- Character variety â Using uppercase, lowercase, numbers, and symbols maximizes entropy.
- Randomness â Avoiding dictionary words and predictable patterns is critical.
- Uniqueness â Never reusing passwords ensures a breach on one site doesn't affect others.
Password Strength Guide
The strength meter evaluates length and character variety. A Very Strong password (green) is 16+ characters with all four character types. Use a password manager like Bitwarden or 1Password to store generated passwords safely â never store them in plain text files.
Privacy & Security
All passwords are generated locally in your browser using the Web Crypto API. No passwords, inputs, or outputs are ever transmitted to any server. This tool is completely stateless and private.
