If I have a user that logged in with email/password is there any way to change that user’s email address on the backend?
I see I can have the user change it themselves with oldEmail, newEmail, password:
ref.changeEmail({
oldEmail : "bobtony#firebase.com",
newEmail : "bobtony#google.com",
password : "correcthorsebatterystaple"
}, function(error) {
if (error === null) {
console.log("Email changed successfully");
} else {
console.log("Error changing email:", error);
}
But is there any way for me to change it for them without the password?
From Firebase support: There is no way to change the user's email address without the password.

My iOS application uses Firebase login by username and password. But I would like to give a possibility to change the username in settings.
The question is, does Firebase support changing a username?
Update
username means email
If you want to change the displayName you can use this code:
let changeRequest = Auth.auth().currentUser?.createProfileChangeRequest()
changeRequest?.displayName = "DoesData"
changeRequest?.commitChanges { (error) in
// ...
}
If you want to change the email address you can use:
currentUser?.updateEmail(email) { error in
if let error = error {
print(error)
}
else {
// Email updated
}
}
I know you have to reauthenticate if you update a users password, but I'm not sure if you need to do that for email changes as well.
This code can help with authentication:
let credential = FIREmailPasswordAuthProvider.credentialWithEmail(email, password: password)
let currentUser = FIRAuth.auth()?.currentUser
currentUser?.reauthenticateWithCredential(credential) { error in
if let error = error {
// An error happened.
} else {
// User re-authenticated.
}
}

I guess you're talking about the email and password auth method.
You can change the email (which is the username) by updating it directly from code. Hope this helps!
I have an Application that uses Firebase for Authentification.
I allow users to sign in with either Google/Facebook/Twitter or using an Email and Password.
Additionally I have activated within Firebase that Users can only create one account per email.
I want to cover the Following case:
A users signs up with facebook and gets a user account created with their facebook email (e.G. facebookuser#gmail.com).
A few days later the user comes back to the app, but forgot that he signed up using facebook and tries loging in with their email adress facebookuser#gmail.com and their usual password instead.
The firebase.auth().signInWithEmailAndPassword(email, password) method throws an auth/wrong-password error, as no password was given using the facebook login method but the email does exist.
Instead of showing a useless "Wrong password or the account corresponding to the email does not have a password set." error I would like to check instead which provider was used for signing up and reminding the user to sign in with the provider instead.
Unfortunately there doesn't seem to exist a method to get the User.ProviderID for a given email or to understand if the auth/wrong-password error was given because the user typed in a wrong password or if there was no password given in first place as the user signed up with an OAuthProvider instead.
Okay, I have missed the fetchProvidersForEmail method.
Just for Reference: (not the final code I will be using)
Uses signInWithEmailAndPassword to check if a User exists
If it doesn't it creates it using createUserWithEmailAndPassword
If a user exits, it tries to login and catches errors
If the error is auth/wrong-password it checks with fetchProvidersForEmail if the user has used a Provider to sign up
firebase.auth().signInWithEmailAndPassword(email, password).catch(function(error) {
var errorCode = error.code;
var errorMessage = error.message;
// User not found? Create user.
if ( errorCode === 'auth/user-not-found' ) {
firebase.auth().createUserWithEmailAndPassword(email, password).catch(function(error) {
// Handle Errors here.
var errorCode = error.code;
var errorMessage = error.message;
if ( errorCode == 'email-already-in-use' ) {
alert('You already have an account with that email.');
} else if ( errorCode == 'auth/invalid-email' ) {
alert('Please provide a valid email');
} else if ( errorCode == 'auth/weak-password' ) {
alert('The password is too weak.');
} else {
alert(errorMessage);
}
console.log(error);
});
// Wrong Password Error
} else if ( errorCode === 'auth/wrong-password' ) {
// Check if User has signed up with a OAuthProvider
firebase.auth().fetchProvidersForEmail(email).then(function( result ){
// … show OAuthProvider Login Button
});
alert('Wrong password. Please try again');
} else {
alert( errorMessage );
}
console.log( error );
});
I am using email & password authentication to logging in user, from my firebase dashboard i have set session expiration time to 2 months . However when i am closing my app from background and then after reopening of app i am getting var user = ref.getAuth(); as null
Does firebase does't take care of this? How to keep user logged in for a long period of time?
Below is the piece of code i am using to login user. I am using react-native
ref.authWithPassword({
email : 'username',
password : 'password'
}, function(error, authData) {
if (error) {
console.log("Login Failed!", error);
} else {
navigatorReference.push({name:'myFeed'})
console.log("Authenticated successfully with payload:", authData);
}
});
Firebase should take care of this. Double check your configuration in the Login & Auth tab in your App Dashboard to make sure you have that setup properly.
You could also try passing along the configuration like so...
ref.authWithPassword({
email : 'username',
password : 'password'
}, function(error, authData) { /* Your Code */ }, {
remember: "default"
});
Basically, I'm using Jquery validation package as a way to alert errors to users when creating and registering accounts on Meteor, since the boilerplate interface doesn't work in my case.
Anyway, when a user tries to sign up for an account, I get no response at all on client. The user is just created with no message or redirection like it's supposed to have.
Here is the particular code:
Template.createAccount.onRendered(function(){
var validator = $('.register').validate({
submitHandler: function(){
user = {
email: document.getElementById("email").value,
password: document.getElementById("password").value
};
Accounts.createUser({
email: user.email,
password: user.password,
function(error){
if(error){
if(error.reason == "Email already exists."){
validator.showErrors({
email: "The email belongs to a registered user."
});
}
} else{
console.log("Account successfully created.");
Router.go("starter");
}
}
});
}
});
})
I'm using the same code logic for account logins with the only exception being a different meteor accounts function (Meteor.loginWithPassword() for login and Accounts.createUser() for account creation).
No response at all, so it probably has to do something with the callback function, since the user account is created, but no message displayed on client.
You're including your callback as part of your options object when it should be a separate argument. It should look more like this:
Accounts.createUser({
email: user.email,
password: user.password
}, function(error){
if(error){
if(error.reason == "Email already exists."){
validator.showErrors({
email: "The email belongs to a registered user."
});
}
} else{
console.log("Account successfully created.");
Router.go("starter");
}
});
I am building user authentication in my website using Angular and Firebase's Email & Password authentication framework. This is NOT using the Firebase Simple Login Framework but the newly introduced native framework.
My code links to Firebase using:
<script src="https://cdn.firebase.com/js/client/1.1.0/firebase.js"></script>
I can create users, login and so on but the ResetPassword call fails with the following error.
Error: Firebase.resetPassword failed: First argument must be a valid object.

The code I use is from the firebase example as follows:
ref.resetPassword(email, function(error) {
if (error === null) {
console.log("Password reset email sent successfully");
} else {
console.log("Error sending password reset email:", error);
}
});
I have verified that a valid email id is being passed in.
Can you please let me know what the issue is?
Thanks in advance

According to the firebase documentation, you should be passing in an object not a string.
https://www.firebase.com/docs/web/api/firebase/resetPassword.html
var credentials = {email: email};
ref.resetPassword(credentials, function(error) {
if (error === null) {
console.log("Password reset email sent successfully");
} else {
console.log("Error sending password reset email:", error);
}
}
I have found that using an object no longer works, it would keep giving me "First argument must contain the key "email", even then the object was as the answer above.
After much frustration i got it working passing the email parameter as per the firebase docs.
$scope.resetPassword = function(email){
console.log("made in to auth method for reset passowrd with email - " + email);
ref.resetPassword({
email: email
}, function(error) {
if (error) {
switch (error.code) {
case "INVALID_USER":
console.log("The specified user account does not exist.");
break;
default:
console.log("Error resetting password:", error);
}
} else {
console.log("Password reset email sent successfully!");
}
});
}
