Let’s Encrypt has introduced short-lived TLS certificates with a 6-day lifetime, now generally available for operators. These certificates, valid for 160 hours, require users to opt-in and select the 'shortlived' profile in their ACME client. The rollout also includes IP address-based certificates, addressing security issues in certificate management.
