This function acquires credentials from the environment in the following order: 1. If the environment variable ``GOOGLE_APPLICATION_CREDENTIALS`` is set to the path of a valid service account JSON private key file, then it is loaded and returned. The project ID returned is the project ID defined in the service account file if available (some older files do not contain project ID information). If the environment variable is set to the path of a valid external account JSON configuration file (workload identity federation), then the configuration file is used to determine and retrieve the external credentials from the current environment (AWS, Azure, etc). These will then be exchanged for Google access tokens via the Google STS endpoint. The project ID returned in this case is the one corresponding to the underlying workload identity pool resource if determinable. If the environment variable is set to the path of a valid GDCH service account JSON file (`Google Distributed Cloud Hosted`_), then a GDCH credential will be returned. The project ID returned is the project specified in the JSON file. 2. If the `Google Cloud SDK`_ is installed and has application default credentials set they are loaded and returned. To enable application default credentials with the Cloud SDK run:: gcloud auth application-default login If the Cloud SDK has an active project, the project ID is returned. The active project can be set using:: gcloud config set project 3. If the application is running in the `App Engine standard environment`_ (first generation) then the credentials and project ID from the `App Identity Service`_ are used. 4. If the application is running in `Compute Engine`_ or `Cloud Run`_ or the `App Engine flexible environment`_ or the `App Engine standard environment`_ (second generation) then the credentials and project ID are obtained from the `Metadata Service`_. 5. If no credentials are found, :class:`~google.auth.exceptions.DefaultCredentialsError` will be raised. .. _Application Default Credentials: https://developers.google.com /identity/protocols/application-default-credentials .. _Google Cloud SDK: https://cloud.google.com/sdk .. _App Engine standard environment: https://cloud.google.com/appengine .. _App Identity Service: https://cloud.google.com/appengine/docs/python /appidentity/ .. _Compute Engine: https://cloud.google.com/compute .. _App Engine flexible environment: https://cloud.google.com /appengine/flexible .. _Metadata Service: https://cloud.google.com/compute/docs /storing-retrieving-metadata .. _Cloud Run: https://cloud.google.com/run .. _Google Distributed Cloud Hosted: https://cloud.google.com/blog/topics /hybrid-cloud/announcing-google-distributed-cloud-edge-and-hosted Example:: import google.auth credentials, project_id = google.auth.default() Args: scopes (Sequence[str]): The list of scopes for the credentials.
