-## Configure AWS Credentials for GitHub Actions
-Configure your AWS credentials and region environment variables for use in other
-GitHub Actions. This action implements the AWS SDK credential resolution chain
-and exports environment variables for your other Actions to use. Environment
-variable exports are detected by both the AWS SDKs and the AWS CLI for AWS API
-calls.
+Configure AWS Credentials
+=========================
+Authenticate to AWS in GitHub Actions! Works especially well with [AWS Secrets
+Manager](https://github.com/aws-actions/aws-secretsmanager-get-secrets).
 
----
+Quick Start (OIDC, recommended)
+-------------------------------
+1. Create an IAM Identity Provider in your AWS account for GitHub OIDC. (See 
+[OIDC configuration](#oidc-configuration) below for details.)
+2. Create an IAM Role in your AWS account with a trust policy that allows GitHub
+Actions to assume it:
+    <details>
+    <summary>GitHub OIDC Trust Policy</summary>
 
-### Recent News
+    ```json
+    {
+      "Version": "2012-10-17",
+      "Statement": [

+          }
+        }
+      ]
+    }
+    ```
+    </details>
+3. Attach permissions to the IAM Role that allow it to access the AWS resources 
+you need.
+4. Add the following to your GitHub Actions workflow:
+    <details>
+    <summary>Example Workflow</summary>
 
-#### Long-term credentials warning (10/3/23)
-
-We have added a warning when using long-term credentials to access AWS
-(IAM access keys and secret keys). Using long-term credentials requires you
-to create IAM users and properly secure the access keys to prevent their disclosure.
-A better approach is to use [GitHub's support for OpenID Connect](#OIDC) to authenticate
-using an IAM role to generate temporary security credentials.
-
-#### v4 Announcement (9/11/23)
-
-We have just released `v4` of Configure AWS Credentials. The only thing that
-changed from `v3` is that the action now runs on `node20` instead of `node16`. If using a self-hosted runner, specify [v2.311.0](https://github.com/actions/runner/releases/tag/v2.311.0) or above for `node20` support.
-You can still see the `v3` announcement below, as it is still recent.
-
-#### v3 Announcement (8/23/23)
-
-We have recently released `v3` of Configure AWS Credentials! With this new
-release we have migrated the code to TypeScript, and have also migrated away
-from using `v2` of the JavaScript AWS SDK. This should eliminate the warning you
-have seen in your workflow logs about `v2` deprecation.
-
-In addition to the refactored codebase, we have also introduced some changes to
-existing functionality, added some new features, and fixed some bugs. These
-changes should be backwards compatible with your existing workflows.
-
-**Notable changes to existing functionality**
-
-- By default, the assumed role credentials will only be valid for one hour in
-_all_ use cases. This is changed from 6 hours in `v2`. You can adjust this value
-with the `role-duration-seconds` input.
-- By default, your account ID will not be masked in workflow logs. This was
-changed from being masked by default in the previous version. AWS does not consider
-account IDs as sensitive information, so this change reflects that stance. You
-can revert to the old default and mask your account ID in workflow logs by
-setting the `mask-aws-account-id` input to `true`.
-
-**New features**
-
-- You can now configure retry settings in case your STS call fails. By default,
-we retry with exponential backoff twelve times. You can disable this behavior
-altogether by setting the `disable-retry` input to `true`, or you can configure
-the number of times the action will retry with the `retry-max-attempts` input.
-- You can now set the returned credentials as action step outputs. To do this,
-you can set the `output-credentials` prop to `true`.
-- There's now an option to clear the AWS-related environment variables at the
-start of the action. Clearing these variables is often a workaround for 
-problems, so enabling this can be helpful if existing credentials or environment
-variables are interfering with the action. You can enable this by setting the
-`unset-current-credentials` input to `true`.
-
-**Bug fixes**
-
-You can find a list of bugs that have been fixed in v3 in the
-[changelog](./CHANGELOG.md).

-## Overview
-We support five methods for fetching credentials from AWS, but we recommend that
-you use GitHub's OIDC provider in conjunction with a configured AWS IAM
-Identity Provider endpoint.
-
-To do that, you would add the following step to your workflow:
-
-```yaml
-    - name: Configure AWS Credentials
-      uses: aws-actions/configure-aws-credentials@v4
-      with:
-        role-to-assume: arn:aws:iam::123456789100:role/my-github-actions-role
-        aws-region: us-east-2
-```
-This will cause the action to perform an [`AssumeRoleWithWebIdentity`](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRoleWithWebIdentity.html) call and
-return temporary security credentials for use by other steps in your workflow. In order for
-this to work, you'll need to preconfigure the IAM Identity Provider in your AWS account
-(see the [OIDC](https://github.com/aws-actions/configure-aws-credentials#OIDC) section below for details).
-
-You can use this action with the AWS CLI available in
-[GitHub's hosted virtual environments](https://help.github.com/en/actions/reference/software-installed-on-github-hosted-runners) or run this action multiple times
-to use different AWS accounts, regions, or IAM roles in the same GitHub Actions
-workflow. As an example, here is a complete workflow file that uploads artifacts
-to Amazon S3.
-
-```yaml
-jobs:
-  deploy:
-    name: Upload to Amazon S3
-    runs-on: ubuntu-latest
-    # These permissions are needed to interact with GitHub's OIDC Token endpoint.
+    ```yaml
+    # Need ID token write permission to use OIDC
     permissions:
       id-token: write
-      contents: read
-    steps:
-    - name: Checkout
-      uses: actions/checkout@v3
-    - name: Configure AWS credentials from Test account
-      uses: aws-actions/configure-aws-credentials@v4
-      with:
-        role-to-assume: arn:aws:iam::111111111111:role/my-github-actions-role-test
-        aws-region: us-east-1
-    - name: Copy files to the test website with the AWS CLI
-      run: |
-        aws s3 sync . s3://my-s3-test-website-bucket
-    - name: Configure AWS credentials from Production account
-      uses: aws-actions/configure-aws-credentials@v4
-      with:
-        role-to-assume: arn:aws:iam::222222222222:role/my-github-actions-role-prod
-        aws-region: us-west-2
-    - name: Copy files to the production website with the AWS CLI
-      run: |
-        aws s3 sync . s3://my-s3-prod-website-bucket
+    jobs:
+      run_job_with_aws:
+        runs-on: ubuntu-latest
+        steps:
+          - name: Configure AWS Credentials
+            uses: aws-actions/configure-aws-credentials@main # Or a specific version
+            with:
+              role-to-assume: <Role ARN you created in step 2>
+              aws-region: <AWS Region you want to use>
+          - name: Additional steps
+            run: |
+              # Your commands that require AWS credentials
+              aws sts get-caller-identity 
+    ```
+    </details>
+That's it! Your GitHub Actions workflow can now access AWS resources using the
+IAM Role you created. Other authentication scenarios are also supported (see
+below).
+
+Security Recommendations
+------------------------
+* Use temporary credentials when possible. OIDC is recommended because it
+  provides temporary credentials and it's easy to set up.
+* Do not store credentials in your repository's code. Consider using
+  [git-secrets](https://github.com/awslabs/git-secrets) to prevent committing
+  secrets to your repository.
+* [Grant least privilege](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#grant-least-privilege)
+  to your workflows. Grant only those permissions that are necessary for the
+  workflow to run.
+* [Monitor the activity](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#keep-a-log)
+  of the credentials used in workflows.
+* Periodically rotate any long-lived credentials that you use.
+* Store sensitive information in a secure way, such as using
+  [AWS Secrets Manager](https://aws.amazon.com/secrets-manager/) or
+  [GitHub Secrets](https://docs.github.com/en/actions/security-guides/encrypted-secrets).
+
+Other Authentication Scenarios
+------------------------------
+This action supports five different authentication methods that are configured
+by specifying different inputs.
+
+1. Use a `core.getIDToken()` call to authenticate via OIDC.
+2. Re-export existing long-lived IAM credentials (access key ID and secret
+   access key) as environment variables.
+3. Use static credentials stored in GitHub Secrets to fetch temporary
+   credentials via STS AssumeRole.
+4. Use a Web Identity Token to fetch temporary credentials via STS
+   AssumeRoleWithWebIdentity.
+5. Use credentials stored in the Action environment to fetch temporary
+   credentials via STS AssumeRole.
+
+Because we use the AWS JavaScript SDK, we always will use the [credential
+resolution flow for Node.js](https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/setting-credentials-node.html).
+Depending on your inputs, the action might override parts of this flow.
+

+
+#### Adjust the retry mechanism
+You can configure retry settings for if the STS call fails. By default, we
+retry with exponential backoff `12` times. You can disable this behavior
+altogether by setting the `disable-retry` input to `true`, or you can configure
+the number of times it retries with the `retry-max-attempts` input.
+
+#### Mask account ID
+Your account ID is not masked by default in workflow logs. You can set the
+`mask-aws-account-id` input to `true` to mask your account ID in workflow logs
+if desired.
+
+#### Unset current credentials
+Sometimes, existing credentials in your runner can get in the way of the
+intended outcome. You can set the `unset-current-credentials` input to `true` to

-### Note about GHES
+#### Special characters in AWS_SECRET_ACCESS_KEY
+Some edge cases are unable to properly parse an `AWS_SECRET_ACCESS_KEY` if it
+contains special characters. For more information, please see the
+[AWS CLI documentation](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-troubleshooting.html#tshoot-signature-does-not-match).
+If you set the `special-characters-workaround` option, this action will
+continually retry fetching credentials until we get one that does not have
+special characters. This option overrides the `disable-retry` and
+`retry-max-attempts` options. We recommend that you do not enable this option
+unless required, because retrying APIs infinitely until they succeed is not best
+practice.
 
-Some of this documentation may be inaccurate if you are using GHES (GitHub Enterprise Servers), please take note to review the GitHub documentation when relevant.
+Session Naming and Policies
+---------------------------
+The default session name is "GitHubActions", and you can modify it by specifying
+the desired name in `role-session-name`.
 
-For example, the URL that the OIDC JWT is issued from is different than the usual `token.actions.githubusercontent.com`, and will be unique to your enterprise server. As a result, you will need to configure this differently when you create the Identity Provider.
+*Note: you might find it helpful to set the `role-session-name` to `${{ github.run_id }}` 
+so as to clarify in audit logs which AWS actions were performed by which workflow 
+run.*
 
-## Security recommendations
-
-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.
-  * [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.
-  * [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.
-
-## Using this action
-There are five different supported ways to retrieve credentials:
-
-- Using GitHub's OIDC provider (`AssumeRoleWithWebIdentity`)
-- Proceeding as an IAM user (No STS call is made)
-- Using access keys as action input (`AssumeRole`)
-- Using a WebIdentity Token File (`AssumeRoleWithWebIdentity`)
-- Using existing credentials in your runner (`AssumeRole`)
-
-We recommend using [GitHub's OIDC provider](https://docs.github.com/en/actions/deployment/security-hardening-your-deployments/configuring-openid-connect-in-amazon-web-services) to get short-lived AWS credentials needed for your actions. See [OIDC](#OIDC) for more information on how to setup your AWS account to assume a role with OIDC. 
-
-The following table describes which method is used based on which values are supplied to the Action:
-
-| **Identity Used**                                               | `aws-access-key-id` | `role-to-assume` | `web-identity-token-file` | `role-chaining` | `id-token` permission
-| --------------------------------------------------------------- | ------------------- | ---------------- | ------------------------- | - | - |

-| IAM User                                                        | ✔                   |                  |                           | | |
-| Assume Role using IAM User credentials                          | ✔                   | ✔                |                           | | |
-| Assume Role using WebIdentity Token File credentials            |                     | ✔                | ✔                         | | |
-| Assume Role using existing credentials | | ✔ | | ✔ | |
-
-*Note: `role-chaining` is not necessary to use existing credentials in every use case. If you're getting a "Credentials loaded by the SDK do not match" error, try enabling this prop.

+Session policies are not required, but they allow you to limit the scope of the

+session policy by its ARN.
 
 #### Inline session policies

-### Misc
+OIDC Configuration
+-------------------
+We recommend using [GitHub's OIDC
+provider](https://docs.github.com/en/actions/deployment/security-hardening-your-deployments/configuring-openid-connect-in-amazon-web-services)
+to get short-lived AWS credentials needed for your actions. When using OIDC, you
+configure IAM to accept JWTs from GitHub's OIDC endpoint. This action will
+then create a JWT unique to the workflow run using the OIDC endpoint, and it
+will use the JWT to assume the specified role with short-term credentials. 
 
-#### Adjust the retry mechanism
-You can now configure retry settings for when the STS call fails. By default, we retry with exponential backoff `12` times. You can disable this behavior altogether by setting the `disable-retry` input to `true`, or you can configure the number of times it retries with the `retry-max-attempts` input.
+To get this to work
+1. Configure your workflow to use the `id-token: write` permission.
+2. Configure your audience, if required.
+3. In your AWS account, configure IAM to trust GitHub's OIDC identity provider.
+4. Configure an IAM role with appropriate claim limits and permission scope.
 
-#### Mask account ID
-Your account ID is not masked by default in workflow logs since it's not considered sensitive information. However, you can set the `mask-aws-account-id` input to `true` to mask your account ID in workflow logs if desired.
+   *Note*: Naming your role "GitHubActions" has been reported to not work. See
+   [#953](https://github.com/aws-actions/configure-aws-credentials/issues/953).
 
-#### Unset current credentials
-Sometimes, existing credentials in your runner can get in the way of the intended outcome, and the recommended solution is to include another step in your workflow which unsets the environment variables set by this action. Now if you set the `unset-current-credentials` input to `true`, the workaround is made eaiser
+5. Specify that role's ARN when setting up this action.
 
-#### Special characters in AWS_SECRET_ACCESS_KEY
-Some edge cases are unable to properly parse an `AWS_SECRET_ACCESS_KEY` if it
-contains special characters. For more information, please see the
-[AWS CLI documentation](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-troubleshooting.html#tshoot-signature-does-not-match).
-If you set the `special-characters-workaround` option, this action will
-continually retry fetching credentials until we get one that does not have
-special characters. This option overrides the `disable-retry` and
-`retry-max-attempts` options.

-```
-
-### Audience
-
-When the JWT is created, an audience needs to be specified. By default, the audience is `sts.amazonaws.com` and this will work for most cases. Changing the default audience may be necessary when using non-default AWS partitions. You can specify the audience through the `audience` input:

-### Sample IAM OIDC CloudFormation Template
-To use GitHub's OIDC provider, you must first set up federation
-with the provider in as an IAM IdP. The GitHub OIDC provider only needs to be
-created once per account (i.e. multiple IAM Roles that can be assumed by the
-GitHub's OIDC can share a single OIDC Provider).
+### Configuring IAM to trust GitHub
+To use GitHub's OIDC provider, you must first set up federation in your AWS
+account. This involves creating an IAM Identity Provider that trusts GitHub's
+OIDC endpoint. You can create an IAM Identity Provider in the AWS Management 
+Console by specifying the following details:
+- **Provider Type**: OIDC
+- **Provider URL**: `https://token.actions.githubusercontent.com`
+- **Audience**: `sts.amazonaws.com` (or your custom audience if you specified
+  one in the `audience` input)
 
-Note that the thumbprint has been set to all F's because the thumbprint is not
-used when authenticating `token.actions.githubusercontent.com`. Instead, IAM
-uses its library of trusted CAs to authenticate. However, this value is still
-required by the API.
+Prior versions of this documentation gave instructions for specifying the
+certificate fingerprint, but this is no longer necessary. The thumbprint, if 
+specified, will be ignored.
 
-This CloudFormation template will configure the IdP for you. You can copy the
-template below, or load it from here:

 ### Claims and scoping permissions
-To align with the Amazon IAM best practice of [granting least privilege](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#grant-least-privilege), the assume role policy document should contain a [`Condition`](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition.html) that specifies a subject (`sub`) allowed to assume the role. [GitHub also recommends](https://docs.github.com/en/actions/deployment/security-hardening-your-deployments/about-security-hardening-with-openid-connect#defining-trust-conditions-on-cloud-roles-using-oidc-claims) filtering for the correct audience (`aud`). See [AWS IAM documentation](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_iam-condition-keys.html#condition-keys-wif) on which claims you can filter for in your trust policies.

-Without a subject (`sub`) condition, any GitHub user or repository could potentially assume the role. The subject can be scoped to a GitHub organization and repository as shown in the CloudFormation template. However, scoping it down to your org and repo may cause the role assumption to fail in some cases.

You can also [customize your subject claim](https://docs.github.com/en/actions/deployment/security-hardening-your-deployments/about-security-hardening-with-openid-connect#customizing-the-token-claims) if you want full control over the information you can filter for in your trust policy. If you aren't sure what your subject (`sub`) key is, you can add the [`actions-oidc-debugger`](https://github.com/github/actions-oidc-debugger) action to your workflow to see the value of the subject (`sub`) key, as well as other claims.

-## Self-Hosted Runners
+Examples
+--------
 
-If you run your GitHub Actions in a
-[self-hosted runner](https://help.github.com/en/actions/hosting-your-own-runners/about-self-hosted-runners) that already has access to AWS credentials, such as
-an EC2 instance, then you do not need to provide IAM user access key credentials
-to this action. We will use the standard AWS JavaScript SDK credential
-resolution methods to find your credentials, so if the AWS JS SDK can
-authenticate on your runner, this Action will as well.
-
-If no access key credentials are given in the action inputs, this action will
-use credentials from the runner environment using the
-[default methods for the AWS SDK for Javascript](https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/setting-credentials-node.html).
-
-You can use this action to simply configure the region and account ID in the
-environment, and then use the runner's credentials for all AWS API calls made by
-your Actions workflow:
-```yaml
-uses: aws-actions/configure-aws-credentials@v4
-with:
-  aws-region: us-east-2
-```
-In this case, your runner's credentials must have permissions to call any AWS
-APIs called by your Actions workflow.
-
-Or, you can use this action to assume a role, and then use the role credentials
-for all AWS API calls made by your Actions workflow:
-```yaml
-uses: aws-actions/configure-aws-credentials@v4
-with:
-  aws-region: us-east-2
-  role-to-assume: my-github-actions-role
-```
-In this case, your runner's credentials must have permissions to assume the
-role.
-
-You can also assume a role using a web identity token file, such as if using
-[Amazon EKS IRSA](https://docs.aws.amazon.com/eks/latest/userguide/iam-roles-for-service-accounts-technical-overview.html). Pods running in EKS
-worker nodes that do not run as root can use this file to assume a role with a
-web identity.
-
-### Proxy Configuration
-
-If you run in self-hosted environments and in secured environment where you need
-use a specific proxy you can set it in the action manually.
-
-Additionally this action will always consider already configured proxy in the
-environment.
-
-Manually configured proxy:
-```yaml
-uses: aws-actions/configure-aws-credentials@v4
-with:
-  aws-region: us-east-2
-  role-to-assume: my-github-actions-role
-  http-proxy: "http://companydomain.com:3128"
-```
-
-Proxy configured in the environment variable:
-```bash
-# Your environment configuration
-HTTP_PROXY="http://companydomain.com:3128"
-```
-
-The action will read the underlying proxy configuration from the environment and
-you don't need to configure it in the action.
-
-### Use with the AWS CLI
-This workflow does _not_ install the [AWS CLI](https://aws.amazon.com/cli/)
-into your environment. Self-hosted runners that intend to run this action prior
-to executing `aws` commands need to have the AWS CLI
-[installed](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-install.html)
-if it's not already present. 
-Most [GitHub hosted runner environments](https://github.com/actions/virtual-environments)
-should include the AWS CLI by default.
