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.

are you sure this mandates always using a new private key? I think I have read that they don't. how would you verify that anyway?
