How to replicate django authentication in several services - django

Question

We have a web app using Django. We have the authentication system setup as described below. Now, we would like to take some part of the application to an independent service, but we would like to have the same valid token/authentication system. The new service will be using Django too, probably, so I would like to know if this is even possible or what options do I have to implement this behavior.
In the case that we do not use Django in the new service, there would be a way to still use the same logic to authenticate requests on the two services?
Authentication system
Right now, we are authenticating the requests using the rest_framework module, more precisely, the TokenAuthentication class.
This is the configuration:
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
...
'rest_framework',
'rest_framework.authtoken',
...
}
REST_FRAMEWORK = {
'DEFAULT_PERMISSION_CLASSES': (
'rest_framework.permissions.IsAuthenticated'
),
'DEFAULT_AUTHENTICATION_CLASSES': (
'module.authentications.AuthorizedAuthentication',
)
}
And the code we use to authorize the requests:
import logging
from rest_framework.authentication import TokenAuthentication
from rest_framework.exceptions import AuthenticationFailed
class AuthorizedAuthentication(TokenAuthentication):
def authenticate(self, request):
response = TokenAuthentication.authenticate(self, request)
if response is None:
return None
return response
To authenticate in the views, we do something like this:
from rest_framework.permissions import IsAuthenticated
from rest_framework.views import APIView
class SomeView(APIView):
permission_classes = (IsAuthenticated,)
EDIT
The code is not complete so please do not comment about it, I have just copied to show you a simplified example about our configuration.
