Replace Phone Auth with Email Link Auth

[MikeAlvarado]

Hey there !

We are migrating users from phone to emailLink auth.

At the moment for existing users we are able to create another auth instance (user) on firebase if we do the emailLink, but as expected the previous user instance (phone) is replaced with the emailLink one

We are aware of the linkWithCredential method but documentation shows how to update credentials apart from the emailLink method.

Was wondering what is the best way to do this?

What we thought was to first update the email, with updateEmail and then try using the emailLink for later signing ins

We went for a firebaseAdmin function on our server to updateEmail and then login in normally.
