You have multiple authentication backends configured and therefore must provide the `backend` argument or set the `backend` attribute on the user.

I get this error when trying to activate a new user from verification code:

You have multiple authentication backends configured and therefore must provide the backendargument or set thebackend attribute on the user.

I’ve updated my activate function to specify the default authentication channel but still no luck:

def activate(request, uidb64, token, backend='django.contrib.auth.backends.ModelBackend'):

@omab, correct! Solved it by dropping authenticate() and taking the user from my form:

if form.is_valid():
    user = form.save()
    login(request, user, backend='django.contrib.auth.backends.ModelBackend')
