From today until March 15, 2026, the maximum lifetime for a TLS certificate is 398 days.

As of March 15, 2026, the maximum lifetime for a TLS certificate will be 200 days.

As of March 15, 2027, the maximum lifetime for a TLS certificate will be 100 days.

As of March 15, 2029, the maximum lifetime for a TLS certificate will be 47 days.

What's everyone's opinion on this? I think from a security standpoint their reasoning is valid and in many cases it's very easy to automate the renewal with ACME or something else. But there's likely gonna be legacy stuff still around in 2029 that won't be easy to automate.

I am a little concerned about the fact that Let's encrypt is a centralized service subject to outages. What would happen if they we either breached or had a several day issue.

If you are in the cloud you can use the cloud provided certs

and I'm a little more concerned about the fact that Let's Encrypt has lost its funding recently

Out of the 2 scenarios this is the more immediate concern for me

This is always a concern however we were recently stung by the dicicert revocation thing. Spending a night changing thousands of certs was not fun
