Model Message at migration

Using Django Getting Started

My Model is like below.

from django.db import models
from django.contrib.auth.models import AbstractUser

# Create your models here.

class User(AbstractUser):
    GENDER_CHOICES = (
        ('M', 'Male'),
        ('F', 'Female'),
        ('O', 'Other'),
    )

    USER_TYPE = (
        ('S', 'Super Admin'),
        ('A', 'Admin'),
        ('P', 'Patient'),
        ('D', 'Doctor'),
        ('U', 'User'),
    )

    first_name = models.CharField(max_length=255)
    last_name = models.CharField(max_length=255)
    date_of_birth = models.DateField()
    gender = models.CharField(max_length=1, choices=GENDER_CHOICES)
    user_type = models.CharField(max_length=1, choices=USER_TYPE)
    email = models.EmailField(unique=True)
    phone = models.CharField(max_length=15, blank=True, null=True)
    address = models.TextField(blank=True, null=True)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    active = models.BooleanField(default=True)



    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []


    def __str__(self):
        return f"{self.first_name} {self.last_name}"

I am getting message like below.

It is impossible to add a non-nullable field 'password' to user without specifying a default. This is because the database needs something to populate existing rows.
Please select a fix:
 1) Provide a one-off default now (will be set on all existing rows with a null value for this column)
 2) Quit and manually define a default value in models.py.

Is there a question here? If so, what is it?

What did this model look like before this most recent change? (What is the change you made for which you’re running makemigrations?)
