Adding this in settings.py fixed it for me

AUTHENTICATION_BACKENDS = (
    "django.contrib.auth.backends.ModelBackend",
    "allauth.account.auth_backends.AuthenticationBackend"
)

The tutorial you've pointed requires you to create a superuser in section 1.2, so create one for yourself and then use those informations on your login.

In your terminal you will type: python manage.py createsuperuser

Then you will be prompted as follows:

Username (leave blank to use 'ubuntu'): <YOUR_USERNAME>
Email address: <email> // you can leave it as blank
Password: <YOUR_PASSWORD>
Password (again): <YOUR_PASSWORD>

Then call again, replacing those values between <> with your input values:

curl -X POST -d "username=<YOUR_USERNAME>&password=<YOUR_PASSWORD>" http://127.0.0.1:8000/api/auth/login/
