Django- Disabling confirm password

I followed the example below copied from the now-defunct Documentation site. The example is too good - here two password fields are used.

I don't want to use confirm password. I only want to use single password field. Is there any way to do that?

Update

RegistrationForm in forms.py uses inbuilt UserCreationForm. It contains two password fields.

Custom user model with email as primary login field

models.py :

from __future__ import unicode_literals
from django.db import models
from django.contrib.auth.models import (
        AbstractBaseUser, BaseUserManager, PermissionsMixin)
from django.utils import timezone
from django.utils.translation import ugettext_lazy as _


class UserManager(BaseUserManager):
    def _create_user(self, email,password, is_staff, is_superuser, **extra_fields):
        now = timezone.now()
        if not email:
            raise ValueError('users must have an email address')
        email = self.normalize_email(email)
        user = self.model(email = email,
                            is_staff = is_staff,
                            is_superuser = is_superuser,
                            last_login = now,
                            date_joined = now,
                            **extra_fields)
        user.set_password(password)
        user.save(using = self._db)
        return user

    def create_user(self, email, password=None, **extra_fields):
        user = self._create_user(email, password, False, False, **extra_fields)
        return user

    def create_superuser(self, email, password, **extra_fields):
        user = self._create_user(email, password, True, True, **extra_fields)
        return user

class User(AbstractBaseUser,PermissionsMixin):
    """My own custom user class"""

    email = models.EmailField(max_length=255, unique=True, db_index=True, verbose_name=_('email address'))
    date_joined = models.DateTimeField(auto_now_add=True)
    is_active = models.BooleanField(default=True)
