Strong Password Generator

Create random, hard-to-crack passwords using your browser's built-in cryptographic randomness (crypto.getRandomValues). Passwords are generated locally and never leave your device.

Strength

What makes a password strong?

Length beats complexity. A 16-character password mixing letters, numbers, and symbols has so many combinations that brute-forcing it is infeasible. Never reuse passwords across sites — use a password manager to store the unique ones this tool generates.

Frequently asked questions

Is this password generator safe?

Yes. It uses the Web Crypto API for true cryptographic randomness, and runs entirely in your browser. The password is never transmitted, logged, or stored.

How long should my password be?

At least 12 characters; 16+ is recommended for important accounts. Longer is always stronger.

Can I generate passwords offline?

Yes — once the page is loaded you can disconnect from the internet and it still works.
