Putting Auth0 Login in front of Google Form

I want to put auth0 in front of a Google Form. What is the best way to do this?
We have a Wordpress based website, so I could use Auth0 with Wordpress, or some of our applications use Django and I’ve used Auth0 there. I successfully made a Django application that implements Auth0 and then redirects the user to our form, but this seems like overkill.
What is the suggested way to do this?
