Connecting Django with Firebase Authentication

Firebase is a service created by google to help developers developing their apps. Firebase can store various data and helps store user information including authentication.

In this article we will be using Firebase for authentication in a Django app. First, we will create an account through Firebase Dashboard. We will discuss account creation through Django later.

Head to Firebase Dashboard > Authentication then press Add User and fill the email and password. Once you create an account, the UID will be generated automatically and Signed in field will be empty for now.

Next, we want to authenticate this newly created account through Django.

To send an authentication request to Firebase with Django, we will use the post method from requests library in python. We will send this request to firebase API and save the idToken that was given in return. This idToken will be saved in the client’s browser cookie and will be used to verify a user’s session. We can then show different part in the app that can only be accessed by an authenticated user by using the cookie that was saved. Some other method might be better and safer but this method will be enough for demonstration.

First, we need to create a form for the user’s sign in input by using the following code in both the views.py and index.html. In index.html we will use Django Template Language to show different text depending if the user is authenticated or not. In views.py we can use the cookie that was saved in the user’s browser to verify the user. You also need to add this view in urls.py

Once we’re done, we can test it if it works. If the authentication is successful, the page will not show the form again but will instead welcome the user. You can also see that in the Firebase Dashboard, the Signed in field is filled with the last login.

That is all! I hope this article is useful. Have a nice day!
