Django User Authentication System | Django Tutorials

What is the Django User authentication system? To understand user authentication, we have to know about authentication. It is the way in which we check or validate a user wheater, it is a registered user or not.  we can also say that Authentication is the process of recognizing a user’s identity which means, we are want to know that who is coming to use the system? If you are using pure programming while developing an application, then you need to write pure coding from basic to end to authenticate a user. But we are learning Django, which makes it easy for us because Django provides us a complete User authentication system that involves user accounts, groups, permissions, and cookie-based user sessions.

Authentication System Types

There are different types of Authentication systems, it depends upon the situation and type of your project then we use. All type of authentication has the same purpose which is to authenticate a command user from outside into private system.

  • Password-based authentication
  • Biometric authentication
  • Multi-factor authentication
  • Certificate-based authentication
  • Token-based authentication

When we have a chance to write tutorials after selected, Surely we will create easy tutorials on types of authentication systems for beginners.

Authorization | Detailed Discussion Django User Authentication System

Django not provides only an authentication system but also provide a complete authorization system also. In a simple way, authorization means, after authentication we check what valid users have rights to do in the system. Actually, authorization is referred to provide different privileges to the user that what responsibility a user has in the system.

For example, sometimes, you are a valid user, you are allowed to publish a post, edit a post, delete a post. But you don’t allow to delete another user post because you have don’t right to do, here authorization system is work. Because the admin did not provide a right to the user to delete any one user’s post. So the authentication is used to check a valid or invalid user but authorization is involving in providing permissions or rights to the user after becoming a valid user.

How to Django User Authentication System Install in Django project

To use an authentication system, you have to use a control module, for this, you have to import django.conrtib.auth. To use an authentication system you have to install it first, otherwise, such functionality as provided by Django, you cannot use it. So, in this section, we will tell you how you can install it in your Django project. It is very best for you because by default all the required configuration is written in the settings.py file of your Django project file.

When you run a command Django-admin startproject projectname, then all the Django authentication system required settings are created for your project. So, you don’t need to do this. But it is very important to know that where its settings and how you can do settings if you did not find the default setting.

‘django.contrib.auth’: It contains default models in which all the user-related information is stored related for its authentication. and also it contains an authentication framework core.
‘django.contrib.contenttypes’: It contains all the permissions that are related to models when we create. When you create models, we can do different operations that may be applied as create, read, update and delete. Such kind of permission is allowed to users. Models contain permissions-related information is stored here.

In your middleware list, you have to include two middleware, it did not find them. Surely, you will find them by default when you start a new project.

MIDDLEWARE = [

‘django.contrib.sessions.middleware.SessionMiddleware’, #Manages sessions across requests

‘django.contrib.auth.middleware.AuthenticationMiddleware’, #Associates users with requests using sessions.
….

]

Now you have to run a migrate command as following:

python manage.py migrate

It will create all necessary tables in which default data related to the user authentication system will store.
