-
-1. Add a top-level `permissions` key that requests a GitHub OIDC ID token:
-
-   ```yaml
-   permissions:
-     id-token: write
-   ```
-
-1. Define a job that triggers the OIDC exchange. Update `connection_id`
-   with the connection ID you copied from Docker:
-
-   ```yaml
-   jobs:
-     login:
-       runs-on: ubuntu-latest
-       steps:
-         - name: OIDC connections
-           id: docker_oidc
-           uses: docker/oidc-action@v1
-           with:
-             connection_id: <YOUR_CONNECTION_ID>
-   ```
-
-1. Add a step that signs in to Docker with an access token once the ID
-   token passes authentication:
-
-   ```yaml
-   - name: Sign in to Docker Hub
-     uses: docker/login-action@{{% param "login_action_version" %}}
-     with:
-       username: <DOCKER_ORGANIZATION_NAME>
-       password: ${{ steps.docker_oidc.outputs.token }}
-   ```
-
-   The `username` value must be an organization name. Personal accounts
-   aren't supported.
-
-   Your updated workflow YAML should look like this:
-
-   ```yaml
-   permissions:
-     id-token: write
-
-   jobs:
-     login:
-       runs-on: ubuntu-latest

-         - name: Sign in to Docker Hub

-             password: ${{ steps.docker_oidc.outputs.token }}
-   ```
-
-1. Run your GitHub Action and verify the workflow can sign in to Docker.
+### Step 2: Update your workflow
+
+Add the OIDC connection ID and your Docker organization name as
+[GitHub Actions variables](https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/store-information-in-variables)
+in your repository or organization settings. Then update your workflow:
+
+```yaml
+permissions:
+  contents: read
+  id-token: write
+
+steps:
+  -
+    name: Login to Docker Hub
+    uses: docker/login-action@v4
+    env:
+      DOCKERHUB_OIDC_CONNECTIONID: ${{ vars.DOCKERHUB_OIDC_CONNECTIONID }}
+    with:
+      username: ${{ vars.DOCKERHUB_ORGANIZATION }}
+```
+
+The `id-token: write` permission lets the workflow request a GitHub OIDC
+token. The `docker/login-action` handles the OIDC token exchange and
+Docker login in a single step when `DOCKERHUB_OIDC_CONNECTIONID` is set
+and `password` is omitted.
+
+The `username` value must be an organization name. Personal accounts
+aren't supported.
+
+Run your GitHub Action and verify the workflow can sign in to Docker.
+
+> [!TIP]
+> If your workflow needs the Docker access token as a separate output
+> (for example, for API calls or custom authentication flows), use
+> [`docker/oidc-action`](https://github.com/docker/oidc-action) to
+> perform the token exchange explicitly.
