Extending Django's user model should be done early in projects. I use AbstractBaseUser for full control or AbstractUser to extend the default. Setting AUTH_USER_MODEL points Django to my custom model. I add fields like phone, avatar, or preferences. For profile data, I sometimes use a separate Profile model with OneToOneField. Custom user managers handle creation logic. I ensure username/email uniqueness constraints. Migrations become complex if changing user models mid-project. This provides flexibility for auth requirements.
