Add Actalis
Request an Actalis EAB key pair and connect it to aethercert as an ACME certificate authority, and what its free tier's single-domain limit means in practice.
Actalis issues certificates over ACME but requires an external account binding key pair first.
Its free tier covers a single domain plus that domain's www variant. That suits one
site; it does not suit a fleet, so plan on Actalis being one authority among several
rather than the only one.
1. Request an EAB key pair
2. Connect it in aethercert
3. Use it
Select this authority under Build > Certificate Job for the one domain it covers, and use Let's Encrypt or another authority for everything else.
Exceeding the free tier's domain limit produces an error from Actalis at issuance, so it appears as a failed job rather than as a validation error in the form.
