Let’s Encrypt TLS certificate lifetimes to drop from 90 to 64 days starting February 2027
Websites that rely on Let’s Encrypt will soon have to renew their TLS certificates more often. Starting February 10, 2027, the certificate authority will issue certificates valid for 64 days by default, down from 90 days. Subscribers who already use Let’s Encrypt’s optional 45-day or 6-day certificates are not affected
