Frequently Asked Questions

How secure is this password generator?

It uses the Web Crypto API (crypto.getRandomValues) — the same cryptographic standard used by security applications.

Are generated passwords stored anywhere?

No — passwords are generated entirely in your browser and are never sent to any server.

How long should my password be?

At least 12 characters is recommended. For high-security accounts, use 20+ characters.

What makes a password strong?

A mix of uppercase, lowercase, numbers, and symbols — combined with sufficient length (12+).

Yes, completely free with no sign-up required.

About This Password Generator

Create secure, unpredictable passwords directly in your browser. This tool uses cryptographically secure pseudorandom number generation to ensure your passwords cannot be guessed or predicted.

How It Works

The generator uses the browser's native Web Crypto API (crypto.getRandomValues) to generate true randomness, then maps those random values to your selected character sets. It never relies on Math.random(), which is predictable and insecure for passwords.

Best Practices for Secure Passwords

Use at least 16 characters for high-security accounts (email, banking)
Never reuse passwords across different services
Use a password manager to store the generated passwords
Enable Two-Factor Authentication (2FA) wherever possible

Privacy & Security

This tool operates entirely on the client side (in your browser). Passwords are never sent across the internet, logged in our servers, or saved in any database. The moment you close the tab, your generated password is gone forever.
