Don't mean to intrude, but I just wanted to chime in that the password security, when derived from Math.random(), is low:

Math.random() does not provide cryptographically secure random numbers. Do not use them for anything related to security. Use the Web Crypto API instead, and more precisely the window.crypto.getRandomValues() method.
