Answer 1

I think this is because you didn't add the middleware in. In your settings.py, find the MIDDLEWARE variable. Under

'django.contrib.auth.middleware.AuthenticationMiddleware',

add

'django_otp.middleware.OTPMiddleware', 

Also make sure do apply the migrations:

python manage.py migrate

Answer 2

You must call authenticate before you can call login.

authenticate sets an attribute on the object, which means backend has successfully validated it and clearing it for login.

Or

you can use is_authenticated

https://docs.djangoproject.com/en/3.2/ref/contrib/auth/

Answer 3

You should add OTPMiddleware just after AuthenticationMiddleware according to the doc as shown below:

# "settings.py"

MIDDLEWARE = [
    ...
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django_otp.middleware.OTPMiddleware' # Here
]
