Error Codes

*
auth/missing-android-pkg-name
*
An Android package name must be provided if the Android app is required * to be installed.
*
auth/missing-continue-uri
*
A continue URL must be provided in the request.
*
auth/missing-ios-bundle-id
*
An iOS bundle ID must be provided if an App Store ID is provided.
*
auth/invalid-continue-uri
*
The continue URL provided in the request is invalid.
*
auth/unauthorized-continue-uri
*
The domain of the continue URL is not whitelisted. Whitelist * the domain in the Firebase console.

Thrown if there already exists an account with the email address * asserted by the credential. Resolve this by calling * {@link firebase.auth.Auth.fetchSignInMethodsForEmail} with the error.email * and then asking the user to sign in using one of the returned providers. * Once the user is signed in, the original credential retrieved from the * error.credential can be linked to the user with * {@link firebase.User.linkWithCredential} to prevent the user from signing * in again to the original provider via popup or redirect. If you are using * redirects for sign in, save the credential in session storage and then * retrieve on redirect and repopulate the credential using for example * {@link firebase.auth.GoogleAuthProvider.credential} depending on the * credential provider id and complete the link.

child_changed event
