Is there any option to implement amazon account linking using firebase, We know we can implement account linking for google, facebook and twitter using firebase auth provider.

I am implementing account linking for google, twitter, facebook using firebase auth. The below code shows

firebase.auth.GoogleAuthProvider()
firebase.auth.FacebookAuthProvider()
firebase.auth.TwitterAuthProvider()

then i am getting result using

firebase.auth().signInWithRedirect(provider)
firebase.auth().getRedirectResult()

I want to link account using amazon login page.Is there any way to do it or please provide any suggestion to show amazon login page then user enter email and password i want to get user data

Answer 1

Firebase Authentication has no built-in provider for Amazon sign-in. That means that, to allow signing in to Firebase with Amazon accounts, you'll have to create a custom provider.

Linking custom provider accounts into existing accounts (from built-in providers) is not currently supported. But if you look at this Github thread, there's some good info on how to accomplish the same by using custom claims or another mechanism.
