About This Generator

Is this password truly random?

Yes. Passwords are generated using crypto.getRandomValues() — the browser's cryptographically secure random number generator (CSPRNG). This is the same entropy source used by cryptographic software. We never use Math.random() for security-sensitive operations.

How long should my password be?

For most accounts, 16–20 characters with a mix of character types provides excellent security. For critical accounts (email, banking, password manager master password), use 24+ characters. Longer is always better, assuming you're using a password manager.

Is my password sent to your servers?

No. Password generation happens entirely in your browser's JavaScript engine. No network requests are made during generation. You can disconnect from the internet and the tool will still work. Verify this by watching the Network tab in your browser's DevTools.
