Django 1.10 - how to change front end user authentication from username to email?

In Django default user authentication is integrated through Username and Password. In my project profile page, I have an option to change Username. So, it is necessary to change my authentication system in back end and front end with email and password.

Using authentication backend i can change default authentication system through email and password in admin. Here is the code -

class EmailBackend(object):
    def authenticate(self, username=None, password=None, **kwargs):
        UserModel = get_user_model()
        try:
            user = UserModel.objects.get(email=username)
        except UserModel.DoesNotExist:
            return None
        else:
            if getattr(user, 'is_active', False) and  user.check_password(password):
                return user
        return None

    def get_user(self, user_id):
        try:
            return User.objects.get(pk=user_id)
        except User.DoesNotExist:
            return None

In settings.py -

AUTHENTICATION_BACKENDS = (
    'apps.account.email-auth.EmailBackend',
)

I was wondering how could i do the authentication through in front end. Already, I prepared front login page through email and password.

But see form.errors and predict must be missing any front authentication like AUTHENTICATION_BACKENDS

Thank you very much for your help!

There is a package django-allauth. It handles the authentication. It allows using 'email' and 'password' or 'username' and 'password' for authentication. It includes forms and everything else needed. Django-cookiecutter project template uses this package to handle authentication, so you can look there and use it as a sample.

Actually answer is within the method -

def authenticate(self, username=None, password=None, **kwargs):

In front-end, naming the user input with email wouldn't be passed within the method then form errors show up with don't match credentials. So, simply taking input as username solves the trick.
