Is a basic random source used?

No. All randomness comes from a cryptographically secure source as required for secure generation.

Are passwords sent to a server?

Never. Generation and display happen only in your browser tab.

What does exclude ambiguous do?

It omits characters like 0, O, 1, l, I that are easy to confuse when reading or typing.

How do passphrases differ from random passwords?

Passphrases use several words and are often easier to remember. A sufficiently long randomly generated password usually provides more strength for its length.
