+  #### Using External Account Authorized User workforce credentials
+
+  [External account authorized user credentials](https://cloud.google.com/iam/docs/workforce-obtaining-short-lived-credentials#browser-based-sign-in) allow you to sign in with a web browser to an external identity provider account via the
+  gcloud CLI and create a configuration for the auth library to use.
+
+  To generate an external account authorized user workforce identity configuration, run the following command:
+
+  ```bash
+  gcloud auth application-default login --login-config=$LOGIN_CONFIG
+  ```
+
+  Where the following variable needs to be substituted:
+  - `$LOGIN_CONFIG`: The login config file generated with the cloud console or
+     [gcloud iam workforce-pools create-login-config](https://cloud.google.com/sdk/gcloud/reference/iam/workforce-pools/create-login-config)
+
+  This will open a browser flow for you to sign in via the configured third party identity provider
+  and then will store the external account authorized user configuration at the well known ADC location.
+  The auth library will then use the provided refresh token from the configuration to generate and refresh
+  an access token to call Google Cloud services.
+
+  Note that the default lifetime of the refresh token is one hour, after which a new configuration will need to be generated from the gcloud CLI.
+  The lifetime can be modified by changing the [session duration of the workforce pool](https://cloud.google.com/iam/docs/reference/rest/v1/locations.workforcePools), and can be set as high as 12 hours.
