#форма авторизвции
class LoginFormView(FormView):
    form_class = AuthenticationForm

    # Аналогично регистрации, только используем шаблон аутентификации.
    template_name = "login.html"

    # В случае успеха перенаправим на главную.
    success_url = "/"

    def form_valid(self, form):
        # Получаем объект пользователя на основе введённых в форму данных.
        self.user = form.get_user()

        # Выполняем аутентификацию пользователя.
        login(self.request, self.user)
        return super(LoginFormView, self).form_valid(form)

<!-- Sign In Form -->
<form>
   <button type='submit' name='submit' value='sign_in'></button>
</form>
<!-- Sign Up Form -->
<form>
   <button type='submit' name='submit' value='sign_up'></button>
</form>

#views.py
def index(request):
    if request.method == "POST":
        if request.POST.get('submit') == 'sign_in':
            # your sign in logic goes here
        elif request.POST.get('submit') == 'sign_up':
            # your sign up logic goes here

PS You already decide whether you have CBV or FBV.
