Temporal has introduced a new feature that allows users to securely generate both CA and end-entity certificates using the Temporal Cloud CLI tool, tcld. This update aims to address the challenges faced by many users in generating these certificates, particularly those without existing certificate management tooling. The process is secure as it runs on the user's local machine, with Temporal never having access to secret keys. Users can now generate mTLS certificates for Temporal Cloud and add them using tcld commands. This feature aims to improve users' experience with Temporal Cloud, with more improvements such as metrics and notifications coming soon.
