How Can I Disable Authentication in Django REST Framework

if you want to disable authentication for a certain class based view, then you can use,

class PublicEndPoint(APIView):
    authentication_classes = [] #disables authentication
    permission_classes = [] #disables permission
    
    def get(self, request):
        pass

This is useful when you want to make only specific endpoints available public.

You can give empty defaults for the permission and authentication classes in your settings.

REST_FRAMEWORK = {
    # other settings...

    'DEFAULT_AUTHENTICATION_CLASSES': [],
    'DEFAULT_PERMISSION_CLASSES': [],
}

You can also disable authentication for particular class or method, just keep blank the decorators for the particular method.

from rest_framework.decorators import authentication_classes, permission_classes

@api_view(['POST'])    
@authentication_classes([])
@permission_classes([])
def items(request):
   return Response({"message":"Hello world!"})

You can also apply it on one specific endpoint by applying it on class or method. Just need to apply django rest framework AllowAny permission to the specific method or class.

views.py

from rest_framework.permissions import AllowAny

from .serializers import CategorySerializer
from catalogue.models import Category   

@permission_classes((AllowAny, ))
class CategoryList(generics.ListAPIView):
    serializer_class = serializers.CategorySerializer
    queryset = Category.objects.all()

You can achieve the same result by using an empty list or tuple for the permissions setting, but you may find it useful to specify this class because it makes the intention explicit.
