Two-Factor Authentication with Authy OneTouch

This application example demonstrates how to implement Two-Factor Authentication on a Python Flask application using Authy OneTouch.

Build Status

Learn more about this code in our interactive code walkthrough.

Quickstart

Create an Authy app

Create a free Twilio account if you haven't already done so.

Create a new Authy application. Be sure to set the OneTouch callback endpoint to http://your-server-here.com/authy/callback once you've finished configuring the app.

Local development

This project is built using the Flask web framework and the SQlite3 database.

  1. To run the app locally, first clone this repository and cd into it.

  2. Create a new virtual environment.

  3. Install the requirements.

    pip install -r requirements.txt
    
  4. Copy the .env_example file to .env, and edit it to include your Authy Application's Production API key. This key can be found right below the Application's name in its Settings menu.

  5. Start the development server.

    ./manage.py runserver
    

To actually process OneTouch authentication requests, your development server will need to be publicly accessible. We recommend using ngrok to solve this problem. Note that in this tutorial only the HTTP address from ngrok will work, so you should start it using this command:

ngrok http -bind-tls=false 5000

Once you have started ngrok, set your Authy app's OneTouch callback URL to use your ngrok hostname, like this:

http://88b37ada.ngrok.io/authy/callback

Run the tests

You can run the tests locally through coverage:

  1. Run the tests.

    $ coverage run manage.py test
    

You can then view the results with coverage report or build an HTML report with coverage html.

That's it!
