Python Client for Twilio Authy Two-Factor Authentication (2FA) API

Documentation for Python usage of the Authy API lives in the official Twilio documentation.

The Authy API supports multiple channels of 2FA:

  • One-time passwords via SMS and voice.
  • Soft token (TOTP via the Authy App)
  • Push authentication via the Authy App

If you only need SMS and Voice support for one-time passwords, we recommend using the Twilio Verify API instead.

More on how to choose between Authy and Verify here.

Authy Quickstart

For a full tutorial, check out either of the Python Authy Quickstarts in our docs:

Authy Python Installation

Install with pip:

$ pip install authy

OR

Download the source code and run the following command from your terminal:

$ python setup.py install

Note that you may need admin permissions to run the above commands.

Usage

To use the Authy client, import AuthyApiClient and initialize it with your production API Key found in the Twilio Console:

from authy.api import AuthyApiClient
authy_api = AuthyApiClient('your_api_key')

authy api key in console

2FA Workflow

  1. Create a user
  2. Send a one-time password
  3. Verify a one-time password

OR

  1. Create a user
  2. Send a push authentication
  3. Check a push authentication status

Phone Verification

Phone verification now lives in the Twilio API and has Python support through the official Twilio helper libraries.

Legacy (V1) documentation here. Verify V1 is not recommended for new development. Please consider using Verify V2.

Notice: Twilio Authy API’s Sandbox feature will stop working on Sep 30, 2021

Twilio is discontinuing the Authy API’s Sandbox, a feature that allows customers to run continuous integration tests against a mock Authy API for free. The Sandbox is no longer being maintained, so we will be taking the final deprecation step of shutting it down on September 30, 2021. The rest of the Authy API product will continue working as-is.

This repo previously used the sandbox API as part of the test suite, but that has been since removed.

You will only be affected if you are using the sandbox API in your own application or test suite.

For more information please read this article on how we are discontinuing the Twilio Authy sandbox API.
