About This Tool

Password Generator is a browser-based tool that creates strong, cryptographically secure random passwords. You can customize the password length (8–64 characters), choose which character types to include (uppercase, lowercase, digits, special characters), and instantly see the password strength rating. It also keeps a history of recently generated passwords for your convenience. All generation happens locally in your browser — no data is ever sent to a server.

Frequently Asked Questions

How does the Password Generator ensure randomness?

The tool uses the Web Crypto API's crypto.getRandomValues() method, which generates cryptographically secure random numbers. This is far more secure than using Math.random(), which is not suitable for security-sensitive applications like password generation.

What password length should I use?

For most online accounts, a password of 16 characters with all character types enabled is recommended. For high-security needs like encryption keys or admin accounts, consider using 24–32 characters. Longer passwords are exponentially harder to crack through brute force.

Are the generated passwords stored or transmitted anywhere?

No. All password generation happens entirely in your browser. The only local storage used is for the recent history feature, which saves passwords in your browser's localStorage. No data is ever sent to any server. You can clear the history at any time.

What does the password strength meter measure?

The strength meter evaluates your password based on length and character diversity. It awards points for longer passwords (8+, 12+, 16+ characters) and for including lowercase, uppercase, digits, and special characters. The combined score determines whether the password is rated Weak, Medium, Strong, or Very Strong.

Why should I include special characters in my password?

Special characters (like !@#$%^&*) significantly increase the character pool from which the password is drawn, making it exponentially harder to crack. A 16-character password using only lowercase letters has about 4.4 × 10^22 combinations, while adding all character types increases it to about 3.4 × 10^30 combinations.
