Django-allauth deprecated their AUTHENTICATION_METHOD in version 65.4 and replaced it with a new setting:

To make way for a future "phone" method, AUTHENTICATION_METHOD was removed in favor of a new LOGIN_METHODS.

I noticed that I still had some warnings being logged while running tests in my project and it seems that they come from usages in dj-rest-auth
