Thanks, but that is just part of the equation. I’m using passport-auth0 and want a way to have a /register controller in my app that calls passport.authenticate(‘auth0’) in a way that communicates to the hosted lock page that it should display a signup instead of login.
E.g., I’d like to be able to do something like passport.authenticate('auth0', {initialScreen: 'SignUp'}) and have that available in the config on the hosted lock page, but the auth0 passport strategy filters out anything it is not specifically designed to accept there.
