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.

Doesn't really affet me much, as my LE cronjob will update the cert either way. Doesn't really matter if it's 90 days or 47 (what a weird number of days)

I only can assume: 1.5 months rounded up, using 31 days a month 31+16=47

So you get half a month to realize that your monthly automated renewal is broken?
