#webdev #flask #opensource #authentication

Hello Coders!

This article presents an open-source project that implements social login for Github and Twitter using Flask and Flask-Dance library. The source code can be downloaded from Github (MIT License) and used in real projects or eLearning activities.

Thanks for reading!

✨ How to use the product

Once the source code is downloaded from the public repository, we
need to create the OAuth applications on Github and Twitter and use the credentials (ApplicationID and SecretKEY) for project configuration.

👉 Github Setup - Create an OAuth App

Sign IN to Github
Access Settings -> Developer Settings -> OAuth Apps
Edit your OAuth App
Set Callback URL: https://localhost:5000/login/github/authorized
Generate a secret key (used in the configuration)

👉 Twitter Setup - Create an OAuth App

Sign IN to Twitter
Access Developer Section
Create a new APP
Edit User authentication settings
Set the OAuth version: v1 or v2 (recommended)
Set Callback URL: https://localhost:5000/login/twitter/authorized

Create a new .env in the root of the project based on .env.sample and save the credentials provided by Github and Twitter. To compile and start the project, follow the steps:

👉 Install modules

$ virtualenv env
$ source env/bin/activate
$ pip3 install -r requirements.txt

👉 Set up the environment for Flask

$ export FLASK_APP=run.py
$ export FLASK_ENV=development

👉 Start the app using HTTPS

$ flask run --cert=adhoc

The --cert=adhoc argument forces Flask to start using HTTPS protocol, required by OAuth redirects for bot platforms.

If all goes well, we should be able to access the app in the browser, authenticate via Github and Twitter and also inspect the information provided by each platform when /ping route is accessed:
