TechLet’s Encrypt to cut certificate lifetimes to 64 days starting in February 2027

Let’s Encrypt plans to reduce free SSL/TLS certificate lifetimes from 90 days to 64, beginning February 10, 2027, with testing starting October 14, 2026. The change should be seamless for administrators using ACME clients that support ARI; those relying on fixed renewal schedules or manual processes need to update them before the rollout.
