 ## Credentials

 We recommend following [Amazon IAM best practices](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html) for the AWS credentials used in GitHub Actions workflows, including:
-* Do not store credentials in your repository's code.  You may use [GitHub Actions secrets](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/creating-and-using-encrypted-secrets) to store credentials and redact credentials from GitHub Actions workflow logs.
-* [Create an individual IAM user](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#create-iam-users) with an access key for use in GitHub Actions workflows, preferably one per repository. Do not use the AWS account root user access key.
+* Do not store credentials in your repository's code.
 * [Grant least privilege](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#grant-least-privilege) to the credentials used in GitHub Actions workflows.  Grant only the permissions required to perform the actions in your GitHub Actions workflows.
-* [Rotate the credentials](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#rotate-credentials) used in GitHub Actions workflows regularly.
 * [Monitor the activity](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#keep-a-log) of the credentials used in GitHub Actions workflows.

 ## Assuming a Role
-If you would like to use the static credentials you provide to this action to assume a role, you can do so by specifying the role ARN in `role-to-assume`.
-The role credentials will then be configured in the Actions environment instead of the static credentials you have provided.
-The default session duration is 6 hours, but if you would like to adjust this you can pass a duration to `role-duration-seconds`.
+We recommend using GitHub's OIDC provider to get short-lived credentials needed for your actions. 
+Specifying `role-to-assume` without providing an `aws-access-key-id` or a `web-identity-token-file` will signal to the action that you wish to use the OIDC provider.
+The default session duration is 1 hour when using the OIDC provider to directly assume an IAM Role.
+The default session duration is 6 hours when using an IAM User to assume an IAM Role (by providing an `aws-access-key-id`, `aws-secret-access-key`, and a `role-to-assume`) .
+If you would like to adjust this you can pass a duration to `role-duration-seconds`, but the duration cannot exceed the maximum that was defined when the IAM Role was created.
 The default session name is GitHubActions, and you can modify it by specifying the desired name in `role-session-name`.
+The default audience is `sts.amazonaws.com` which you can replace by specifying the desired audience name in `audience`.
+
+The following table describes which identity is used based on which values are supplied to the Action:
+
+| **Identity Used**                                                | `aws-access-key-id` | `role-to-assume` | `web-identity-token-file` |

+In this example, the Action will load the OIDC token from the GitHub-provided environment variable and use it to assume the role `arn:aws:iam::123456789100:role/my-github-actions-role` with the session name `MySessionName`.

 In this example, the secret `AWS_ROLE_TO_ASSUME` contains a string like `arn:aws:iam::123456789100:role/my-github-actions-role`.  To assume a role in the same account as the static credentials, you can simply specify the role name, like `role-to-assume: my-github-actions-role`.

-### Permissions for assuming a role
+```yaml
+    - name: Configure AWS Credentials for Beta Customers

+In this example, the audience has been changed from the default to use a different audience name `beta-customers`. This can help ensure that the role can only affect those AWS accounts whose GitHub OIDC providers have explicitly opted in to the `beta-customers` label.
