Is it possible to create an ACME account without requesting a certificate? AFAICT is is not so you cannot use this method unless you have first requested a certificate with some other method. I hope I am wrong!
`certbot register` followed by `certbot show_account` is how you'd do this with certbot.
That is precisely why I wrote this: https://github.com/pawlakus/acmecli
This small tool will allow you to just create, rekey and deactivate your acmev2 account(s).
