Authentication in Django Rest Framework is a process of verifying the identity of a user before granting access to protected resources. This article discusses the various authentications methods provided by Django Rest Framework and how to implement them in your project. Whether you are building an API for mobile applications or web services, understanding authentications is crucial to ensure the security of your application. Read on to learn more about the different authentication options available in Django Rest Framework.

Django Rest Framework (DRF) provides several authentication classes to authenticate incoming HTTP requests. The authenticationn classes are responsible for verifying the authenticity of the request by checking the provided credentials, such as an API key or a username and password.

Here are some of the commonly used authenticationn classes in Django rest Framework:

BasicAuthentication: Authenticates a user based on the provided username and password, encoded in base64.

TokenAuthentication: Authenticates a user based on a token provided in the request header. This is a popular method for API authenticationn.

SessionAuthentication: Authenticates a user based on the Django session framework. This is useful for authenticating web applications.

OAuth2Authentication: Authenticates a user based on an OAuth2 token. This is a popular method for API authenticationn and is used to authenticate API requests from third-party applications.

RemoteUserAuthentication: Authenticates a user based on the authenticationn performed by a reverse proxy server.

You can use the authenticationn classes either globally or on a per-view basis. For example, to use BasicAuthentication globally, you can add the following to your settings file:


You can also use multiple authenticationn classes at the same time. In that case, DRF will try to authenticate the user using each class in the order specified, until one of them succeeds.
