This app is a proof-of-concept implementation of the Django Two-Factor Authentication library. It uses Django 1.7.11 and Python 3.4.4.

1. Clone this project and cd into project directory.
2. Confirm what version of python you have installed (run the command python --version); if not 3.4, download python3 from python.org
3. Create the python virtualenvironment by running virtualenv -p /usr/local/bin/python3 env in your project directory
4. Activate the environment by running source env/bin/activate at the same level as the env directory created by the above command
5. Install project requirements by running pip install -r requirements.txt
6. Start the django server by running python manage.py runserver

With your django server running, visit localhost:8000/books/ a view that will show a list of books but which specifically requires two-factor auth signin.

When prompted to do so, login with username: test_otp and password: password.

You should see a message that you need to enable two-factor authentication.

Next you will get a prompt to start the two-factor auth setup wizard.

Select the option to setup a Token generator.

You'll see a QR code to scan with an app like Google Authenticator, this will link your account with the app. When prompted, enter the 6-digit token that should show up in your app.

Once setup is completed, visit /logout to log the user out, then attempt to visit /books/ to prompt a login.

After entering the username and password it will prompt you for the token from your token generator.

You should see a list of books!

When prompted to do so, login with username: test_sms and password: password.

Select the option to setup authentication with Text message.

Enter your phone number (include the +1 country code).

A fake SMS backend is setup in the project, codes will be logged to the output viewable in the shell where you ran python manage.py runserver.

After entering your phone number it will prompt you to enter the code logged in the server shell.

To confirm behavior, visit /logout, attempt to visit /books/ and complete the login process as the test_sms user.

Right now I am only using two options for two-factor authentication (text message or token generator) and I did not build out the project to send actual text messages. The Django Two-Factor Authentication project has settings for using Twilio for text messages and phone calls for authentication as well as setup documentation for Yubikeys.

Additionally, I'm using the built-in Django user authentication backend so it is only setup to allow users to log in to the django admin site; this means that any additional users created to test with must be created as staff users. To access the admin to make more users run the python manage.py createsuperuser command in your project and follow the instructions to make a new superuser. You shoudl be able to login as that user at /admin. Once you are logged in, admin tool easily lets you create users by selecting Add next to Users under the Authentication and Authorization heading. Make sure to mark any new users as staff users or the login process will not work properly.
