Guest onboarding convert to registered user and link submitted data

Hi,   I would like an anonymous user to fill in a form as part of an onboarding.  When the form has been submitted we would like to present the user with the registration form.  Upon registering, the submitted data in the first form should be linked with this new account.    How would we be able to achieve this?   Thanks!

Have a look at the forgot password module from the marketplace

This module offers the signup functionality as well as the forgot password stuff.

I think this will offer you exactly what you need.
