Does django-allauth provide a basic way of using email/password instead of using the default username/password of Django? (without the need of having a social account)
On this tutorial, http://www.sarahhagstrom.com/2013/09/the-missing-django-allauth-tutorial/#Now_we_can_login_using_Django_or_Facebook, after he set up "Facebook", you see that the basic method is still by username.
django-registration-email has been discontinued due to the give-up of django-registration and they mention to look at django-allauth but I do not see whether you can replace the default django username/password method with only an email/password like this app was doing.
Yes, I'm doing exactly what you asked and it works. I use Allauth without using social account and login with email/password.
The settings for what you want are:
ACCOUNT_AUTHENTICATION_METHOD = "email"
ACCOUNT_EMAIL_REQUIRED = True
ACCOUNT_USERNAME_REQUIRED = False
The username is still internally created but it can be totally transparent to the user.
