Hi @ikerib you should check out Django Rest Framework, their docs are really easy to follow, and they have several packages they recommend for authentication.
DRF: http://www.django-rest-framework.org/
They recommend http://django-rest-auth.readthedocs.org/en/latest/introduction.html for authentication against android/iOS apps or AngularJS single page application which will also work in Ionic framework.
Go give it a try, I'm using it myself on a new project I started today
