How is this done? Ie, to not need any account and still get new/valid certs.

And, on that note, what is the difference between having an account and not? Eg, how might using no accounts harm a production environment?

Just trying to wrap my head around that. Really cool UX for side stuff!

edit: Ah, looks like there is an account involved - it creates one, possibly using your email address. This makes more sense now.
