.. |pypi| image:: https://img.shields.io/pypi/v/google-auth.svg :target: https://pypi.python.org/pypi/google-auth

Installing

You can install using pip_::

$ pip install google-auth

.. _pip: https://pip.pypa.io/en/stable/

For more information on setting up your Python development environment, please refer to Python Development Environment Setup Guide_ for Google Cloud Platform.

Extras

google-auth has few extras that you can install. For example::

$ pip install google-auth[pyopenssl]

Note that the extras pyopenssl and enterprise_cert should not be used together because they use conflicting versions of cryptography_.

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Handles Google server-to-server authentication for accessing Google APIs, supporting OAuth and other credential mechanisms across multiple Python versions.

Low friction: pure-Python wheel, only two runtime dependencies (pyasn1-modules and cryptography), and actively maintained with a release 7 days ago. Supports Python 3.10–3.14.

Apache 2.0 permissive license allows commercial and private use with minimal restrictions; you must retain license notices and may not hold the authors liable.

Usage

pip install google-auth

from google.auth import default
credentials, project = default()

Requires Python >= 3.10; cryptography and pyasn1-modules must be installed (handled by pip).

Verdict: Production-ready authentication library maintained by Google with no known vulnerabilities, low install friction, and broad Python version support. Top-100 PyPI package suitable for any application needing Google API access.

Needs verification

Whether the optional extras (pyopenssl, enterprise_cert) are commonly needed or if base installation suffices for most use cases.
Performance characteristics or latency impact when used in high-throughput server scenarios.
