Firebase Convert Anonymous User Account to Permanent Account Error

Question

Using Firebase for web I can successfully create an anonymous user. I can also create a new email/password user. But when trying to convert an anonymous user to a email/password

Answer 1

After you log in as an Anonymous user, run this code to raise Popup and connect your anon user wit some OAUTH provider

const provider = new firebase.auth.FacebookAuthProvider()
firebase.auth().currentUser.linkWithPopup(provider)
console.log(provider)
