-## "Configure AWS Credentials" Action For GitHub Actions
+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).
 
-Configure AWS credential and region environment variables for use in other GitHub Actions.  The environment variables will be detected by both the AWS SDKs and the AWS CLI to determine the credentials and region to use for AWS API calls.
+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>
 
-**Table of Contents**
+    ```json
+    {
+      "Version": "2012-10-17",
+      "Statement": [
+        {
+          "Effect": "Allow",
+          "Principal": {
+            "Federated": "arn:aws:iam::<AWS_ACCOUNT_ID>:oidc-provider/token.actions.githubusercontent.com"
+          },
+          "Action": "sts:AssumeRoleWithWebIdentity",
+          "Condition": {
+            "StringEquals": {
+              "token.actions.githubusercontent.com:aud": "sts.amazonaws.com",
+              "token.actions.githubusercontent.com:sub": "repo:<GITHUB_ORG>/<GITHUB_REPOSITORY>:ref:refs/heads/<GITHUB_BRANCH>"
+            }
+          }
+        }
+      ]
+    }
+    ```
+    </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>
 
-<!-- toc -->
+    ```yaml
+    # Need ID token write permission to use OIDC
+    permissions:
+      id-token: write
+    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).
 
-<!-- tocstop -->
+Other Authentication Scenarios
+------------------------------
+This action supports five different authentication methods that are configured
+by specifying different inputs.
 
-## Usage
+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.
 
-Add the following step to your workflow:
+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.
+
+<details>
+<summary>Inputs and their effects on the credential resolution flow</summary>

+| role-chaining             | Use existing credentials from the environment to assume a new role.                               |    No    |
+| audience                  | The JWT audience when using OIDC. Used in non-default AWS partitions, like China regions.         |    No    |
+| http-proxy                | An HTTP proxy to use for API calls.                                                               |    No    |
+| mask-aws-account-id       | AWS account IDs are not considered secret. Setting this will hide account IDs from output anyway. |    No    |
+| role-duration-seconds     | The assumed role duration in seconds, if assuming a role. Defaults to 1 hour (3600 seconds). Acceptable values range from 15 minutes (900 seconds) to 12 hours (43200 seconds). |    No    |
+| role-external-id          | The external ID of the role to assume. Only needed if your role requires it.                      |    No    |
+| role-session-name         | Defaults to "GitHubActions", but may be changed if required.                                      |    No    |
+| role-skip-session-tagging | Skips session tagging if set.                                                                     |    No    |

+| output-credentials        | When set, outputs fetched credentials as action step output. (Outputs aws-access-key-id, aws-secret-access-key, aws-session-token, aws-account-id, authenticated-arn, and aws-expiration). Defaults to false.                   |    No    |
+| output-env-credentials       | When set, outputs fetched credentials as environment variables (AWS_REGION, AWS_DEFAULT_REGION, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN). Defaults to true. Set to false if you need to avoid setting/changing env variables. You'd probably want to use output-credentials if you disable this. (NOTE: Setting to false will prevent the aws-account-id from being exported as a step output). |    No    |
+| unset-current-credentials | When set, attempts to unset any existing credentials in your action runner.                       |    No    |
+| disable-retry             | Disabled retry/backoff logic for assume role calls. By default, retries are enabled.              |    No    |
+| retry-max-attempts        | Limits the number of retry attempts before giving up. Defaults to 12.                             |    No    |
+| special-characters-workaround | Uncommonly, some environments cannot tolerate special characters in a secret key. This option will retry fetching credentials until the secret access key does not contain special characters. This option overrides disable-retry and retry-max-attempts. | No |
+| use-existing-credentials  | When set, the action will check if existing credentials are valid and exit if they are. Defaults to false. |    No    |
+</details>
+
+#### 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
+work around this issue.
+
+#### Use an HTTP proxy
+
+If need use an HTTP proxy you can set it in the action manually. Additionally
+this action will always consider the `HTTP_PROXY` environment variable.
+
+<details>
+<summary>Proxy configuration</summary>
+
+Manually configured proxy:
+```yaml
+uses: aws-actions/configure-aws-credentials@v4.3.1
+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"
+```
+</details>
+
+#### 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.
+
+Session Naming and Policies
+---------------------------
+The default session name is "GitHubActions", and you can modify it by specifying
+the desired name in `role-session-name`.
+
+*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.*
+
+The session will be tagged with the
+following tags: (Refer to [GitHub's documentation for `GITHUB_` environment
+variable definitions](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/using-environment-variables#default-environment-variables))
+
+| Key        | Value             |
+| ---------- | ----------------- |
+| GitHub     | "Actions"         |
+| Repository | GITHUB_REPOSITORY |
+| Workflow   | GITHUB_WORKFLOW   |
+| Action     | GITHUB_ACTION     |
+| Actor      | GITHUB_ACTOR      |
+| Branch     | GITHUB_REF        |
+| Commit     | GITHUB_SHA        |
+
+_Note: all tag values must conform to
+[the tag requirements](https://docs.aws.amazon.com/STS/latest/APIReference/API_Tag.html).
+Particularly, `GITHUB_WORKFLOW` will be truncated if it's too long. If
+`GITHUB_ACTOR` or `GITHUB_WORKFLOW` contain invalid characters, the characters
+will be replaced with an '*'._
+
+The action will use session tagging by default unless you are using OIDC.
+
+### Session policies
+Session policies are not required, but they allow you to limit the scope of the
+fetched credentials without making changes to IAM roles. You can specify inline
+session policies right in your workflow file, or refer to an existing managed
+session policy by its ARN.
+
+#### Inline session policies
+An IAM policy in stringified JSON format that you want to use as an inline
+session policy. Depending on preferences, the JSON could be written on a single
+line.
+
+<details>
+<summary>Inline session policy examples</summary>
 
 ```yaml
-    - name: Configure AWS Credentials
-      uses: aws-actions/configure-aws-credentials@v1
+      uses: aws-actions/configure-aws-credentials@v4.3.1
+      with:
+         inline-session-policy: '{"Version":"2012-10-17","Statement":[{"Sid":"Stmt1","Effect":"Allow","Action":"s3:List*","Resource":"*"}]}'
+```
+Or we can have a nicely formatted JSON as well:
+```yaml
+      uses: aws-actions/configure-aws-credentials@v4.3.1
+      with:
+         inline-session-policy: >-
+          {
+           "Version": "2012-10-17",
+           "Statement": [
+            {
+             "Sid":"Stmt1",
+             "Effect":"Allow",
+             "Action":"s3:List*",
+             "Resource":"*"
+            }
+           ]
+          }
+```
+</details>
+
+#### Managed session policies
+The Amazon Resource Names (ARNs) of the IAM managed policies that you want to
+use as managed session policies. The policies must exist in the same account as
+the role.
+
+<details>
+<summary>Managed session policy examples</summary>
+
+```yaml
+      uses: aws-actions/configure-aws-credentials@v4.3.1
+      with:
+         managed-session-policies: arn:aws:iam::aws:policy/AmazonS3ReadOnlyAccess
+```
+And we can pass multiple managed policies likes this:
+```yaml
+      uses: aws-actions/configure-aws-credentials@v4.3.1
+      with:
+         managed-session-policies: |
+          arn:aws:iam::aws:policy/AmazonS3ReadOnlyAccess
+          arn:aws:iam::aws:policy/AmazonS3OutpostsReadOnlyAccess
+```
+</details>
+
+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. 
+
+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.
+
+   *Note*: Naming your role "GitHubActions" has been reported to not work. See
+   [#953](https://github.com/aws-actions/configure-aws-credentials/issues/953).
+
+5. Specify that role's ARN when setting up this action.
+
+### OIDC Audience
+
+When the JWT is created, an audience needs to be specified. Normally, you would
+use `sts.amazonaws.com`, and this action uses this by default if you don't
+specify one. This will work for most cases. Changing the default audience may
+be necessary when using non-default AWS partitions, such as China regions.
+You can specify the audience through the `audience` input:
+
+```yaml
+    - name: Configure AWS Credentials for China region audience
+      uses: aws-actions/configure-aws-credentials@v4.3.1
+      with:
+        audience: sts.amazonaws.com.cn
+        aws-region: cn-northwest-1
+        role-to-assume: arn:aws-cn:iam::123456789100:role/my-github-actions-role
+```
+
+### 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)
+
+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.
+
+You can also create the IAM Identity Provider using the AWS CLI:
+
+```bash
+aws iam create-open-id-connect-provider \
+    --url https://token.actions.githubusercontent.com \
+    --client-id-list sts.amazonaws.com 
+```
+
+### 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. See
+[Example subject claims](https://docs.github.com/en/actions/deployment/security-hardening-your-deployments/about-security-hardening-with-openid-connect#example-subject-claims)
+for specific details on what the subject value will be depending on your
+workflow. 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.
+
+Additional claim conditions can be added for higher specificity as explained in
+the [GitHub documentation](https://docs.github.com/en/actions/deployment/security-hardening-your-deployments/about-security-hardening-with-openid-connect).
+Due to implementation details, not every OIDC claim is presently supported by
+IAM.
+

+Examples
+--------
+
+### AssumeRoleWithWebIdentity
+```yaml
+    - name: Configure AWS Credentials
+      uses: aws-actions/configure-aws-credentials@v4.3.1
       with:
-        aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
-        aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
-        # aws-session-token: ${{ secrets.AWS_SESSION_TOKEN }} # if you have/need it
         aws-region: us-east-2
+        role-to-assume: arn:aws:iam::123456789100:role/my-github-actions-role
+        role-session-name: MySessionName
 ```
+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`.
 
-For example, 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).
-You can also run this action multiple times to use different AWS accounts, regions, or IAM roles in the same GitHub Actions workflow job.
-
-```yaml
-jobs:
-  deploy:
-    name: Upload to Amazon S3
-    runs-on: ubuntu-latest
-
-    steps:
-    - name: Checkout
-      uses: actions/checkout@v2
-
-    - name: Configure AWS credentials from Test account
-      uses: aws-actions/configure-aws-credentials@v1
-      with:
-        aws-access-key-id: ${{ secrets.TEST_AWS_ACCESS_KEY_ID }}
-        aws-secret-access-key: ${{ secrets.TEST_AWS_SECRET_ACCESS_KEY }}
-        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@v1
-      with:
-        aws-access-key-id: ${{ secrets.PROD_AWS_ACCESS_KEY_ID }}
-        aws-secret-access-key: ${{ secrets.PROD_AWS_SECRET_ACCESS_KEY }}
-        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
-```
-
-See [action.yml](action.yml) for the full documentation for this action's inputs and outputs.
-
-## 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.
-* [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`.
-The default session name is GitHubActions, and you can modify it by specifying the desired name in `role-session-name`.
-
-Example:
+### AssumeRole with role previously assumed by action in same workflow
 ```yaml
     - name: Configure AWS Credentials
-      uses: aws-actions/configure-aws-credentials@v1
+      uses: aws-actions/configure-aws-credentials@v4.3.1
+      with:
+        aws-region: us-east-2
+        role-to-assume: arn:aws:iam::123456789100:role/my-github-actions-role
+        role-session-name: MySessionName
+    - name: Configure other AWS Credentials
+      uses: aws-actions/configure-aws-credentials@v4.3.1
+      with:
+        aws-region: us-east-2
+        role-to-assume: arn:aws:iam::987654321000:role/my-second-role
+        role-session-name: MySessionName
+        role-chaining: true
+```
+In this two-step example, the first step will use OIDC to assume the role
+`arn:aws:iam::123456789100:role/my-github-actions-role` just as in the prior
+example. Following that, a second step will use this role to assume a different
+role, `arn:aws:iam::987654321000:role/my-second-role`.
+
+### AssumeRole with static IAM credentials in repository secrets
+```yaml
+    - name: Configure AWS Credentials
+      uses: aws-actions/configure-aws-credentials@v4.3.1
       with:
         aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
         aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}

 ```
-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
-
-In order to assume a role, the IAM user for the static credentials must have the following permissions:
-```json
-{
-    "Version": "2012-10-17",
-    "Statement": [
-        {
-            "Action": [

-                "sts:TagSession"
-            ],

-            "Effect": "Allow"
-        }
-    ]
-}
-```
-
-The role's trust policy must allow the IAM user to assume the role:
-```json
-{
-    "Version": "2012-10-17",
-    "Statement": [
-        {
-            "Sid": "AllowIamUserAssumeRole",
-            "Effect": "Allow",
-            "Action": "sts:AssumeRole",
-            "Principal": {"AWS": "arn:aws:iam::123456789012:user/my-github-actions-user"},
-            "Condition": {
-                "StringEquals": {"sts:ExternalId": "Example987"}
-            }
-        },
-        {
-            "Sid": "AllowPassSessionTags",
-            "Effect": "Allow",
-            "Action": "sts:TagSession",
-            "Principal": {"AWS": "arn:aws:iam::123456789012:user/my-github-actions-user"}
-        }
-    ]
-}
-```
-
-### Session tagging
-The session will have the name "GitHubActions" and be tagged with the following tags:
-(`GITHUB_` environment variable definitions can be [found here](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/using-environment-variables#default-environment-variables))
-
-| Key | Value|
-| --- | --- |
-| GitHub | "Actions" |
-| Repository | GITHUB_REPOSITORY |
-| Workflow | GITHUB_WORKFLOW |
-| Action | GITHUB_ACTION |
-| Actor | GITHUB_ACTOR |
-| Branch | GITHUB_REF |
-| Commit | GITHUB_SHA |
-
-_Note: all tag values must conform to [the requirements](https://docs.aws.amazon.com/STS/latest/APIReference/API_Tag.html). Particularly, `GITHUB_WORKFLOW` will be truncated if it's too long. If `GITHUB_ACTOR` or `GITHUB_WORKFLOW` contain invalid charcters, the characters will be replaced with an '*'._
-
-The action will use session tagging by default during role assumption. You can skip this session tagging by providing `role-skip-session-tagging` as true in the action's inputs:
+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`.
 
+### Retrieving credentials from step output, AssumeRole with temporary credentials
 ```yaml
-      uses: aws-actions/configure-aws-credentials@v1
+    - name: Configure AWS Credentials 1
+      id: creds
+      uses: aws-actions/configure-aws-credentials@v4.3.1
       with:
-        role-skip-session-tagging: true
+        aws-region: us-east-2
+        role-to-assume: arn:aws:iam::123456789100:role/my-github-actions-role
+        output-credentials: true
+    - name: get caller identity 1
+      run: |
+        aws sts get-caller-identity
+    - name: Configure AWS Credentials 2
+      uses: aws-actions/configure-aws-credentials@v4.3.1
+      with:
+        aws-region: us-east-2
+        aws-access-key-id: ${{ steps.creds.outputs.aws-access-key-id }}
+        aws-secret-access-key: ${{ steps.creds.outputs.aws-secret-access-key }}
+        aws-session-token: ${{ steps.creds.outputs.aws-session-token }}
+        role-to-assume: arn:aws:iam::123456789100:role/my-other-github-actions-role
+    - name: get caller identity2
+      run: |
+        aws sts get-caller-identity
 ```
+This example shows that you can reference the fetched credentials as outputs if
+`output-credentials` is set to true. This example also shows that you can use
+the `aws-session-token` input in a situation where session tokens are fetched
+and passed to this action.
 
-## Self-Hosted Runners
-
-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.
-
-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/v2/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@v1
-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@v1
-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.
-
-### 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.

+# cfn-deploy example
+
+Example uses aws-action `configure-aws-credentials` with OIDC federation. Prior to using this example project, the user needs to deploy the [github-actions-oidc-federation-and-role](../federated-setup/github-actions-oidc-federation-and-role.yml) template in the AWS account they want to deploy the CloudFormation template into. Specify the GitHub Organization name, repository name, and the specific branch you want to deploy on.
+
+Within the [github/workflows](./.github/workflows/) directory there is a [compliance.yml](./.github/workflows/compliance.yml) and a [deploy.yml](./.github/workflows/deploy.yml). The deploy.yml file leverages the aws-action `configure-aws-credentials` and accesses GitHub Action Secrets for some of the variables. The compliance.yml runs static application security testing using cfn-guard.
+
+To use the example you will need to set the following GitHub Action Secrets:
+
+| Secret Key | Used With | Description |
+| --------- | -------- | -----------|
+| AWS_ACCOUNT_ID | configure-aws-credentials | The AWS account ID |
+| AWS_DEPLOY_ROLE | configure-aws-credentials | The name of the IAM role |
+| VPC_ID | aws-cloudformation-github-deploy | VPC ID the EC2 Bastion is deployed to |
+| SUBNET_ID | aws-cloudformation-github-deploy | Subnet ID the EC2 Bastion is deployed to |
