I use a plugin / python program

AUTHENTICATION_BACKENDS = (
# AxesStandaloneBackend should be the first backend in the
AUTHENTICATION_BACKENDS list.
'axes.backends.AxesModelBackend',

'django.contrib.auth.email-auth.EmailBackend',
'django.contrib.auth.backends.ModelBackend',
)

email-auth.py

place in project root or

/usr/local/lib/python2.7/site-packages/Django-1.11.29-py2.7.egg/django/contrib/auth

use phone number for the user account id and email address will kick in
automatically

can use either for login with valid password

The username would be both a security risk and too damn long.
