How random are the generated passwords?

Passwords are generated with the Web Crypto API's cryptographically secure random number generator, not a predictable pseudo-random function — the same category of randomness used for encryption keys.

How long should my password be?

Most security guidance now recommends at least 12–16 characters, mixing letters, numbers, and symbols, and using a unique password for every account (ideally stored in a password manager).
