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.

    I’ve got it setup automated on all my external domains, but trying to automate it on my internal-only domain is rather tedious since not only do I NOT want to open a port for it to confirm, but I have 2 other devices/services on the network not behind my primary reverse proxy that share the same cert.

    What In need to do is setup my own custom cron that hits the hosting provider to update the DNS txt entries. Then I need to have it write and restart the services that use the cert. I’ve tried to automate this once before and it did not go so smoothly so I’ve been hesitant on wasting time to try it again… But maybe it’s time to.

    What would be ideal is if I could allow it to be automated just by getting a one time dns approval and storing a local private/public key to prove to them that I’m the owner of the domain or something. Not aware of this being possible though.

      Depends on which DNS service you are using, a plugin might already exist that would do it for you. e.g. I use cloudflare for DNS and certbot is able to automatically set the txt record.
