Email Authentication Backend
Django's default authentication works on username and password fields. Email authentication backend will authenticate users based on email and password.
from django.contrib.auth import get_user_model
class EmailBackend(object):
"""
Custom Email Backend to perform authentication via email
"""
def authenticate(self, username=None, password=None):
user_model = get_user_model()
try:
user = user_model.objects.get(email=username)
if user.check_password(password): # check valid password
return user # return user to be authenticated
except user_model.DoesNotExist: # no matching user exists
return None
def get_user(self, user_id):
user_model = get_user_model()
try:
return user_model.objects.get(pk=user_id)
except user_model.DoesNotExist:
return None
Add this authentication backend to the AUTHENTICATION_BACKENDS setting.
# settings.py
AUTHENTICATION_BACKENDS = (
'my_app.backends.EmailBackend',
...
)
