Use OAuth Plugin for Auth0 more seamlessly

@blake Many thanks for your input.

I did everything as outlined in the setup page plus your suggestions. However, when I try to login this appears

Whereas at https://community.auth0.com/ this is what shows for trying to login (and is intended for my site as well)

Furthermore, I tried to login with my test e-mail and it still requires e-mail auth despite the e-mail is authenticated at Auth0

Do you know how to change it accordingly?
