Headless implementation of Google web login (with support for 2-Step Verification) in Python

py-google-auth exposes a high-level Python module and REST API that can be used for headless login on Google Accounts. The API supports 2-step verification if it is enabled on Google Account being used.

Note: This project is in "alpha" version right now. We are actively developing it and expect it to be beta-ready in next couple of weeks.

License

MIT

The license text is available in LICENSE file in root of this repo.

Installation

To install, run:

$ pip install py-google-auth

(for test):

$ pip install -i https://testpypi.python.org/pypi --extra-index-url https://pypi.python.org/pypi py-google-auth

to update the version:

$ pip install -Ui https://testpypi.python.org/pypi --extra-index-url https://pypi.python.org/pypi py-google-auth

To be able to make requests to API, you will need a token. You need to set it in your system environment for the API to access it and then pass it with every request you make:

export PY_GOOGLE_AUTH_TOKEN='some_token'

Also set a path for storing log files. These files will be created when ever some previously unhandled error will occur, in order to help debugging and fixing the problem. You can create a PR for such errors with the content of the file from your log path:

export PY_GOOGLE_AUTH_LOG_PATH=/path/to/logs/

Usage

Open your terminal and run:

py-google-auth

This will start a gunicorn server, which will listen on localhost:8001 by default. You can change host and port (run py-google-auth -h for information).

Then you can make calls to the api using any HTTP library you like. The docs will contain examples with requests.

Example for an account without two factor auth enabled:

>>> import jsonpickle
>>> import os
>>> import requests

>>> token = os.environ.get('PY_GOOGLE_AUTH_TOKEN')
>>> data = {'email': 'myemail@example.com', 'password': 'myrandompassword', 'token': token}

>>> req = requests.post('http://localhost:8001/login', json=data)
>>> req
<Respose 200>

>>> session_str = req.json()['session']
>>> session = jsonpickle.decode(session_str)
>>> google_play_page = session.get('https://play.google.com/apps/publish')
>>> google_play_page
<Respose 200>

Note: jsonpickle is used to encode python objects into json, since we get an encoded string which contains a request.Session object, we need to use decode to make it an object again.

More examples with other endpoints can be found in docs.

End points

Normal login (without two factor auth).

POST /login --data {'email': email, 'password': password, 'token': token}

If two factor auth is enabled, then next request should go here:

POST /step_two_login --data {'session': session, 'method': method, 'otp': otp, 'token': token}

If you want to use alternate method for two factor, use this before /step_two_login:

POST /change_method --data {'session': session, 'method': method, 'token': token}

Details about response data and status codes can be found in docs.

Supported 2-step verification 'steps'

We support following 'steps' (i.e. methods) offered by Google in 2-step verification:

  • Voice or text message: Verification codes are sent by text message.
  • Backup codes: 10 single-use codes are active at this time, but you can generate more as needed.
  • Google prompt: Get a Google prompt on your phone and just tap Yes to sign in.
  • Authenticator app: Use the Authenticator app to get free verification codes, even when your phone is offline. Available for Android and iPhone.
  • Backup phone: Add a backup phone so you can still sign in if you lose your phone.

Unsupported 2-step verification 'step'

We DONT support following 'step' (i.e. method):

  • Security Key: A Security Key is a small physical device used for signing in. It plugs into your computer's USB port.

Documentation

We are in process of writing documentation, which will be hosted at http://py-google-auth.readthedocs.io/en/latest/.
