Why Use a Strong Password?

A strong password should be at least 12 characters long with a mix of uppercase, lowercase, numbers, and symbols. This generator uses the crypto.getRandomValues() API for cryptographic randomness.

How to Use

Set your desired password length using the slider. Check the character types you want to include: uppercase letters, lowercase letters, numbers, and symbols. Click "Generate" to create a secure random password. Click "Copy" to copy it to your clipboard.

Password Strength Tips

A strong password should be at least 12 characters long and include a mix of all character types. Longer passwords are exponentially harder to crack — a 16-character password with mixed types would take billions of years to brute force with current technology. Never reuse passwords across different websites.

How This Generator Works

This password generator uses the browser's built-in crypto.getRandomValues() API for cryptographic randomness, which is more secure than Math.random(). All generation happens locally in your browser — no data is sent to any server, ensuring your passwords remain completely private.
