Prevent SessionID cookie from being sent with JWT token HttpOnly Cookies on Login

[ghost]

Wondering if it is possible to disable the "sessionID" cookie from being sent after the user hits the login endpoint for dj-rest-auth (for my use case this is one of the social login endpoints).

Currently the login endpoint is sending back the following cookies:

• crsftoken
• auth_token
• refresh_token
• sessionID (not needed)
• messages (probably not needed?)

I do not want to remove session authentication completely since if a user logs in through admin they should be able to still use their session authentication. I just want to prevent users logging in through dj-rest-auth social (jwt cookie based) login from receiving these cookies (so that they don't have both session and jwt cookie auth on at the same time).

My settings look as follow:

MIDDLEWARE = [
    "django.middleware.security.SecurityMiddleware",
    "django.contrib.sessions.middleware.SessionMiddleware",
    "corsheaders.middleware.CorsMiddleware",
    "django.middleware.common.CommonMiddleware",
    "django.middleware.csrf.CsrfViewMiddleware",
    "django.contrib.auth.middleware.AuthenticationMiddleware",
    "django.contrib.messages.middleware.MessageMiddleware",
    "django.middleware.clickjacking.XFrameOptionsMiddleware",
]

REST_FRAMEWORK = {
    "DEFAULT_AUTHENTICATION_CLASSES": (
        "dj_rest_auth.jwt_auth.JWTCookieAuthentication",
        "rest_framework.authentication.SessionAuthentication",
    ),
    "DEFAULT_PERMISSION_CLASSES": [
        "rest_framework.permissions.IsAuthenticated",
    ],
}

# dj-rest-auth jwt auth settings
REST_USE_JWT = True
JWT_AUTH_COOKIE = "app-auth-token"
JWT_AUTH_REFRESH_COOKIE = "app-refresh-token"
JWT_AUTH_COOKIE_USE_CSRF = True
JWT_AUTH_HTTPONLY = True
REST_SESSION_LOGIN = False

Sincere apologies if I am misunderstanding something here or not configuring the settings properly, I am still new to this library. I looked through the documentation and didn't find a configuration for this.

The methods complete_social_login (in dj-rest-auth) and django_login (in allauth) are called (see two links below) causing the session cookie to be set, as per standard djagno login flow.

dj-rest-auth/dj_rest_auth/registration/serializers.py

Line 151 in b72a55f

complete_social_login(request, login)

My solution is to have a custom allauth account adapter and set it in my django app settings.

from allauth.account.adapter import DefaultAccountAdapter

class DefaultAccountAdapterCustom(DefaultAccountAdapter):

    def login(self, request, user):
        pass

    def get_login_redirect_url(self, request):
        return None

ACCOUNT_ADAPTER = 'somewhere.in.your.project.DefaultAccountAdapterCustom'

This particular implementation of using the adapter to override login didn't work for me, since it looks like the session is being created before the custom login is called. My solution is to delete the session in custom login method

from allauth.account.adapter import DefaultAccountAdapter

class DefaultAccountAdapterCustom(DefaultAccountAdapter):
  def login(self, request, user):
    del request.session

I came accross the same issue, for me I am trying to delete both session and csrf cookie by below code by overriding DefaultAccountAdapter.

    def login(self, request, user):
        # HACK: Django Allauth is Doing a session login which is not required for this case Hence removing this.
        # Authentication will be performed by Dj-rest-auth in the end
        super().login(request, user)
        request.session.flush()
        request.META.update({
            "CSRF_COOKIE_USED": False,
            "CSRF_COOKIE": None,
        })
        request.csrf_cookie_needs_reset = False

I believe it would be better to be handled by dj-rest-auth as sessions / csrf are not expected if we have set SESSION_LOGIN as False.
The issue occurs for social Logins.
