How is this different from the basic password generator?

This tool guarantees at least one character from each selected group and shuffles the result to avoid predictable patterns.

Entropy (measured in bits) quantifies password strength. Each additional bit doubles the guessing difficulty. 80+ bits is considered Very Strong.

Is the generated password sent anywhere?

No — the password is generated entirely in your browser using JavaScript and never transmitted.
