Feature: Allow custom fields to be added to the new hosted universal SignUp forms
Description: The new universal login experience pages are great, however it would be useful to be able to customize the hosted signup forms to allow for custom fields to be added.
Use-case: GDPR means I can’t automatically subscribe users to a newsletter. I want to be able to offer the user a checkbox where they can opt-in to receive a newsletter when they are on the universal signup form. (But not on the login form)
