Login or register using phone or email for django, allauth integration

Question

I want to change my django user model to allow registration / registration by phone or email. Using

USERNAME_FIELD = 'identifier'

If a user logs in with a phone number, the identifier will be his phone number or email address, vice versa. (If someone thinks I should just assign some number as an identifier, let me know.)

Here are my accounts:

from django.db import models
from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin, BaseUserManager
from phonenumber_field.modelfields import PhoneNumberField

class UserManager(BaseUserManager):
    def create_user(self, email, phone, password, **kwargs):
        """
        Creates and saves a Account with the given email or phone and password.
        """
        now = timezone.now()
        identifier = ''
        if not email:
            if not phone:
                raise ValueError('Users must have a valid email or phone address.')
            else:
                identifier = phone
        if not phone:
            if not email:
                raise ValueError('Users must have a valid email or phone address.')
            else: 
                email = self.normalize_email(email)
                identifier = email

        user = self.model(email=email, phone=phone, 
                            identifier=identifier,
                            joined=now,
                            **kwargs
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, password, **kwargs):
        user = self.model(
            email=email,
            is_staff=True,
            is_superuser=True,
            **kwargs
        )
        user.set_password(password)
        user.save(using=self._db)
        return user

class User(AbstractBaseUser, PermissionsMixin):
    email = models.EmailField(null=True, blank=True, unique=True)
    phone = PhoneNumberField(null=True, blank=True, unique=True)
    joined = models.DateTimeField(auto_now_add=True)
    first_name = models.CharField(max_length=200, null=True, blank=True)
    last_name = models.CharField(max_length=200, null=True, blank=True)
    is_staff = models.BooleanField(default=False)
    objects = UserManager()
    identifier = models.CharField(max_length=40, unique=True)
    USERNAME_FIELD = 'identifier'

    def get_username(self):
        return self.email
    def get_short_name(self):
        return self.first_name
    short_name = property(fget=get_short_name)
