Decreasing Certificate Lifetimes to 45 Days (letsencrypt.org)

Let’s Encrypt will be reducing the validity period of the certificates we issue. We currently issue certificates valid for 90 days, which will be cut in half to 45 days by 2028.
This change is being made along with the rest of the industry, as required by the CA/Browser Forum Baseline Requirements, which set the technical requirements that we must follow. All publicly-trusted Certificate Authorities like Let’s Encrypt will be making similar changes. Reducing how long certificates are valid for helps improve the security of the internet, by limiting the scope of compromise, and making certificate revocation technologies more efficient.

But how to automate wildcard certificate generation? That requires a change of the txt record and namecheap for instance got no mechanism for that to automatically happen on cert bot action

There are some nameserver providers that have an API.

When you register a domain, you can choose which nameserver you like. There are nameservers that work with certbot, choose one that does.

Namecheap supports this according to docs. I just haven't tested yet.

Doesn't caddy support that (name cheap txt mod) via a plug-in?

I haven't tried it yet, but the plugin made it sound possible. I'm planning to automate on next expiration... When I get to it ;)

I did already compile caddy with the plugin, just haven't generated my name cheap token and tested.

"when i get to it" is my time frame aswell, till then its a reoccurring calendar notification with instructions because past me who set this all up was a genius compared to sleep deprived current me

I definitely know that feeling.

Now that I'm at a keyboard, here's the (Caddy) plugin I was referring to : https://github.com/caddy-dns/namecheap
