Password Generator

A password generator creates cryptographically random passwords using secure entropy sources, ensuring each password is unique and practically impossible to guess.

This generator uses the Web Crypto API's getRandomValues() function, which draws entropy from the operating system's secure random number generator. All generation happens client-side in your browser with no network requests. The generated password never leaves your device.

Frequently Asked Questions

How does the password generator work?

The password generator uses the Web Crypto API's getRandomValues() function to generate cryptographically secure random passwords entirely in your browser. No data is sent to any server. The passwords exist only on your device.

What makes a password secure?

A secure password is at least 16 characters long, uses a mix of uppercase letters, lowercase letters, numbers, and symbols, and is unique to each account. Avoid dictionary words, names, and number sequences.

Is it safe to use an online password generator?

This generator is safe because it runs entirely in-browser with no network requests. The password never leaves your device. You can verify this by going offline and testing it — it still works.

How many possible combinations does a 16-character password have?

A 16-character password using 94 printable ASCII characters has 94 to the power of 16 possible combinations, which is approximately 37 septillion possibilities. That is effectively impossible to brute-force with current hardware.
