Ephemeral Values in Terraform

This technical article details the introduction of ephemeral values in Terraform 1.10, including ephemeral input variables, outputs, and a new ephemeral resource type. It explains the security problem they solve by preventing sensitive information from being written to Terraform state or saved plan files, outlines syntax and use cases (like within provider or provisioner blocks), and lists initial provider support from AzureRM, AWS, GCP, and Vault.
