I'm writing this down because I always get flustered.
python - AuthAlreadyAssociated Exception in Django Social Auth - Stack Overflow
https://stackoverflow.com/questions/13018147/authalreadyassociated-exception-in-django-social-auth
Basically, it's as described in this article.
If you're using torico_id_login (TORICO company authentication library):
# If AuthAlreadyAssociated occurs
※ This error won't occur if the user who is already logged in logs out before logging in again.
Two approaches
A: Force the user to log out (e.g., using Middleware)
B: Handle the error in the Auth Pipeline
## A: Force the user to log out
Add the following to MIDDLEWARE_CLASSES in settings:
'submodules.torico_id_login.middleware.SocialAuthExceptionMiddleware',
## B: Handle the error in the Auth Pipeline
Write the following in settings:
SOCIAL_AUTH_PIPELINE = (
'social.pipeline.social_auth.social_details',
'social.pipeline.social_auth.social_uid',
'social.pipeline.social_auth.auth_allowed',
'submodule.torico_id_login.pipeline.social_user',
'social.pipeline.user.get_username',
'social.pipeline.user.create_user',
'social.pipeline.social_auth.associate_user',
'social.pipeline.social_auth.load_extra_data',
'social.pipeline.user.user_details',
)
Like this.
Now,

logout(request)
# Redirect somewhere
return_url = getattr(
settings, 'SOCIAL_AUTH_AAA_URL', getattr(
settings, 'SOCIAL_AUTH_LOGIN_REDIRECT_URL', '/'))
return http.HttpResponseRedirect(return_url)
return super(SocialAuthExceptionMiddleware, self).process_exception(
exception, AuthAlreadyAssociated)
