Overview OpenID Connect (OIDC) allows your GitHub Actions workflows to access resources in Amazon Web Services (AWS), without needing to store the AWS credentials as long-lived GitHub secrets. This guide explains how to configure AWS to trust GitHub's OIDC as a federated identity, and includes a workflow example for the aws-actions/configure-aws-credentials that uses tokens to authenticate to AWS

Overview of OpenID Connect GitHub Actions workflows are often designed to access a cloud provider (such as AWS, Azure, GCP, or HashiCorp Vault) in order to deploy software or use the cloud's services. Before the workflow can access these resources, it will supply credentials, such as a password or token, to the cloud provider. These credentials are usually stored as a secret in GitHub, and the wor
