AWS Certificate Manager now supports the ACME protocol for automated provisioning of public TLS certificates with 45-day validity using standard ACME clients.

  • Provision fully managed ACME server endpoints issuing public TLS certificates from Amazon Trust Services
  • Compatible with ACMEv2 clients including Certbot, cert-manager for Kubernetes, and acme.sh
  • Enables automated certificate issuance and renewal ahead of CA/Browser Forum's 2029 47-day lifetime mandate
  • PKI administrators can define domain scopes, enforce wildcard policies, and delegate requests to teams
  • Domain validation performed once at endpoint level; application owners use standard ACME clients
  • Full auditability with ACM console visibility, CloudTrail logging, and CloudWatch metrics

ACME support in ACM eliminates manual certificate management by providing standards-based automation for certificate lifecycle management.
