This is a client library for accessing resources protected by OAuth 2.0.

Note: oauth2client is now deprecated. No more features will be added to the libraries and the core team is turning down support. We recommend you use google-auth and oauthlib. For more details on the deprecation, see oauth2client deprecation.

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

oauth2client is a client library for accessing resources protected by OAuth 2.0, enabling authentication and authorization flows for Google APIs and other OAuth 2.0-compliant services.

Installation is straightforward with low friction—a pure-wheel distribution with five stable runtime dependencies (httplib2, pyasn1, pyasn1-modules, rsa, six). However, the package is abandoned as of 2019 and no longer receives maintenance or feature updates.

Licensed under Apache 2.0 (permissive), allowing commercial and private use with minimal restrictions, though the abandoned status means no ongoing legal or security review from the maintainers.

Usage

pip install oauth2client==4.1.3

from oauth2client.client import OAuth2WebServerFlow
flow = OAuth2WebServerFlow(client_id='...', client_secret='...', scope='...')

Package is deprecated and abandoned since 2019; Google recommends migrating to google-auth and oauthlib instead.

Verdict: oauth2client is a low-friction, permissively licensed OAuth 2.0 client, but it is abandoned (last release September 2018, repository archived) and explicitly deprecated by Google in favor of google-auth and oauthlib. Use only for legacy systems; new projects should adopt the recommended alternatives.

Needs verification

Whether existing deployments using oauth2client 4.1.3 face known security gaps since the 2019 cutoff.
Compatibility status with Python 3.10+ despite classifiers only listing up to 3.5.
