NEW SSL/TLS CERTS TO EACH LIVE NO LONGER THAN 47 DAYS BY 2029

Summary from the TLDR InfoSec newsletter

The Browser Forum voted to reduce SSL/TLS certificate validity from the current 398 days to just 47 days by 2029. The phased reduction begins in March 2026 with 200-day limits, dropping to 100 days in 2027. Tech giants unanimously supported the change to enhance security by limiting abuse of compromised certificates, though sysadmins worry about increased workload without automation.
