How to change email in firebase auth?

问题

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.

回答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('you@domain.com', 'correcthorsebatterystaple')
    .then(function(userCredential) {
        userCredential.user.updateEmail('newyou@domain.com')
    })

You can do this directly with AngularFire2, you just need to add "currentUser" to your path.

this.af.auth.currentUser.updateEmail(email)
.then(() => {
  ...
});

You will also need to reauthenticate the login prior to calling this as Firebase requires a fresh authentication to perform certain account functions such as deleting the account, changing the email or the password.

For the project I just implemented this on, I just included the login as part of the change password/email forms and then called "signInWithEmailAndPassword" just prior to the "updateEmail" call.

To update the password just do the following:

this.af.auth.currentUser.updatePassword(password)
.then(() => {
  ...
});
