About entropy. The generated password has 6 bits of entropy. Can be cracked quickly. Increase length or include more character types.

How we generate. We use crypto.getRandomValues() from the Web Crypto API — the browser's cryptographically secure generator. Never use Math.random() (predictable) or send passwords to the server.
