## AI overview

The article argues that organizations should start preparing for post-quantum authentication by inventorying certificate dependencies, assessing vendor readiness, and testing interoperability in non-production environments. It describes Microsoft's PQC TLS Pilot Program, which lets eligible certificate authorities evaluate certificate issuance and compatibility; pilot certificates are not for production or public trust.
