Terraform Cloud has introduced support for multiple configurations with unique dynamic credentials for the same provider within a single workspace, addressing the limitation of only one set of credentials per provider and workspace. This enhancement allows users to authenticate multiple aliases of the same provider across different regions and accounts, or targeting multiple clusters within the same provider. Users can now configure workspaces with environment variables to manage dynamic credential management, enabling secure provisioning workflows with Terraform and its providers. The new feature is particularly useful for managing credentials in environments where multiple instances of the AWS provider need unique roles.
