Custom user model can't login after creation

I'm trying to login with an account with my new custom user model. My superuser I created with my user model logs in just fine. However when I create non superuser account through the admin panel and try to login with exact credentials it fails.

Here is my code:

accounts/models.py

from django.db import models
from django.contrib.auth.models import (
    AbstractBaseUser, 
    BaseUserManager,
    PermissionsMixin,
)

# Create your models here.


class UserManager(BaseUserManager):
    def create_user(self, email, first_name, last_name, company, phone, is_active=True, is_admin=False, is_staff=False, is_dealer=False, password=None):
        if not email:
            raise ValueError("Users must have an email address")
        if not password:
            raise ValueError("Users must have a password")
        if not first_name:
            raise ValueError("Users must have a first name")
        if not last_name:
            raise ValueError("Users must have a last name")
        if not company:
            raise ValueError("Users must have a company")
        if not phone:
            raise ValueError("Users must have a phone number")
        user_obj = self.model(
            email = self.normalize_email(email)
        )
        user_obj.set_password(password)
        user_obj.first_name = first_name
        user_obj.last_name = last_name
        user_obj.company = company
        user_obj.phone = phone
        user_obj.admin = is_admin
        user_obj.staff = is_staff
        user_obj.dealer = is_dealer
        user_obj.active = is_active
        user_obj.save(using=self._db)
        return user_obj
