.. _stateless_user_authentication:
Stateless User Authentication
=============================
JWTStatelessUserAuthentication backend
--------------------------------------
The ``JWTStatelessUserAuthentication`` backend's ``authenticate`` method does not
perform a database lookup to obtain a user instance. Instead, it returns a
``rest_framework_simplejwt.models.TokenUser`` instance which acts as a
stateless user object backed only by a validated token instead of a record in a
database. This can facilitate developing single sign-on functionality between
separately hosted Django apps which all share the same token secret key. To
use this feature, add the
``rest_framework_simplejwt.authentication.JWTStatelessUserAuthentication`` backend
(instead of the default ``JWTAuthentication`` backend) to the Django REST
Framework's ``DEFAULT_AUTHENTICATION_CLASSES`` config setting:
.. code-block:: python
REST_FRAMEWORK = {
...
'DEFAULT_AUTHENTICATION_CLASSES': (
...
'rest_framework_simplejwt.authentication.JWTStatelessUserAuthentication',
)
...
}
v5.1.0 has renamed ``JWTTokenUserAuthentication`` to ``JWTStatelessUserAuthentication``,
but both names are supported for backwards compatibility
