How to change email in firebase auth?

Question

I am trying to change/update a user's email address using :

firebase.auth().changeEmail({oldEmail, newEmail, password}, cb) 

But I am getting ...changeEmail is not a function error. I found the reference here from the old firebase docu.

So how to I do it in the 3.x version? Because I cant find a reference in the new documentation.

Answer 1

You're looking for the updateEmail() method on the firebase.User object: https://firebase.google.com/docs/reference/js/firebase.User#updateEmail

Since this is on the user object, your user will already have to be signed in. Hence it only requires the password.

Simple usage:

firebase.auth()     .signInWithEmailAndPassword('[email protected]', 'correcthorsebatterystaple')     .then(function(userCredential) {         userCredential.user.updateEmail('[email protected]')     }) 

Answer 2

If someone is looking for updating a user's email via Firebase Admin, it's documented over here and can be performed with:

admin.auth().updateUser(uid, {   email: "[email protected]" });
