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.

You could try using the DNS challenge instead; I find it a lot more convenient as not all my services are exposed.

While I do have some control over my DNS and can create arbitrary TXT entries, I can't to that in an automated way easily. I'm using Gandi.net to host my DNS rather than running my own DNS sever(s).

EDIT: Gandi is listed https://community.letsencrypt.org/t/dns-providers-who-easily-integrate-with-lets-encrypt-dns-validation/86438 so maybe I can automate a DNS-01 challenge without too much issue, I just have to switch away from certbot to one of the other tools.
