That's because django-allauth has nothing to do with django-rest-framework-jwt. The settings you've set inside settings.py was belong the django-allauth so if you want to use those settings, then you should use django-allauth views.

With django-rest-framework-jwt views, I've taken a look on obtain_jwt_token view and I've seen that they're using get_user_model().USERNAME_FIELD to get the username field.

from django.contrib.auth import get_user_model

def get_username_field():
    try:
        username_field = get_user_model().USERNAME_FIELD
    except AttributeError:
        username_field = 'username'

    return username_field

So if you want to change username field to another one, you could create a custom User model and then set the value for USERNAME_FIELD to email to allow user to login via email instead of username. Like so:

app_name/models.py

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

class User(AbstractUser):
    USERNAME_FIELD = 'email'

    def __str__(self):
        return self.email

and on your settings.py:

AUTH_USER_MODEL = 'app_name.User'
