I\'m using httpie to test my custom authentication.
http POST http://127.0.0.1:8000/api-token-auth/ username=\'username1\' password=\'Password123\'
OK I solved it. Inside my settings, I just had to remove the AUTHENTICATIONS_BACKEND. I thought my custom backend was different for merely logging a user in and the token authentication backend worked to get that token.
