Let's Encrypt is cutting certificate lifetimes to 64 days, so I automated my renewals
If you've been putting this off like I had, it's time
For months, I had ignored the numerous "Your connection is not private" warnings that appeared when accessing my homelab devices. However, Let's Encrypt announced that their certificates would become shorter, going from 90 to 64 days in February 2027 and further down to 45 days in 2028. Realizing that many of my devices lacked trusted certificates, I decided to automate the renewal process.
After testing and adjustments, all three devices successfully transitioned to the new 64-day certificates. To ensure compatibility with different systems, I registered separate Cloudflare API tokens for each device, allowing for independent certificate management without relying on a single account.
