User authentication is a crucial aspect of web development, ensuring that only authorized users can access certain parts of a web application. Django, a powerful Python web framework, provides a robust system for handling user authentication. This blog post will guide you through the process of implementing user authentication in Django.
Django's authentication system handles both authentication (verifying who a user is) and authorization (what a user is allowed to do). It provides a set of views and forms for common tasks such as logging in, logging out, and password management.
Django comes with a built-in User model for authentication. However, if you need to add extra fields to the User model, you can extend it using a one-to-one link.
"You can use Django's `authenticate()` function to verify a set of credentials. If the credentials are valid, the function returns a User object."
Django provides a built-in view,
login(), that you can use for handling user login.
Django also provides a built-in view,
logout(), for handling user logout. When called, it will log out the user and display a 'You are logged out' message.
Django's authentication system comes with views for password change and password reset. The
password_change() view uses the
PasswordChangeForm form and requires the old password and two instances of the new password.
Implementing user authentication in Django is straightforward thanks to Django's robust authentication system. With built-in views and forms for common tasks, you can have a secure authentication system up and running in no time. In our next post, we will explore how to deploy a Django application.
