Allow non-anonymous users to link/upgrade to passwordless email credential
Is your feature request related to a problem? Please describe. I would like to allow users to validate/link passwordless email to existing accounts that have previously been linked to federated oauth providers.
Describe the solution you'd like In the same way an anonymous user can be linked to a credential via "upgrade", we would like to link to the current user even though they are no longer anonymous. We need a confirmed email and Facebook does not always provide that. Many times, we get Facebook users with only a name and photo. In this case, we need to put the UI back in front of the user to add the email.
Describe alternatives you've considered We have considered not using this module and writing our own flow for this, but that defeats the purpose of using such a great package. We also considered unlinking the Facebook login to achieve this, but then we lose those additional provider details like name, photo, and other permissions.
