Can 2-Factor Authorization be used for external registrations via an API?

Q: Can 2-Factor Authorization be used for external registrations via an API?

A: No. 2-Factor Authorization is a feature only applicable for quick registration pages.

Since each registration page can have its own settings, the API does not have any knowledge as to what settings to utilize when registering a user. Therefore, when API is used for registration through an external page, all registrants will be registered immediately.
