From attribute inside node mailer message not working always keep sending mail through default account which is used for creating account - express

let message={
text:'Please join the meeting',
subject:`You are Invited for ${meetingName}`,
Above is my message object the from attribute is not working. I want to send email from logged in user to the user given by him , but node mailer uses the email (my email which is configured at auth) it must use email given in from tag.
const config={
auth: {
pass: ""
always uses instead of logged in user


React Native Expo Push notification for specific user

Expo allows you to send notification by device id which is ambiguous and not great for my use case, how can i send notification that only specific user will receive? for example can i pass user id or username besides device id?
this is the body request body:
to: pushToken, // user id or topic?
body: 'test notification',
data: { withSome: 'data' }
You have to create a db table where you'll record user_id / username & device_token in order to be able to send notification to a user by his user_id or username.

Cognito unable to signup users that have unconfirmed status already

A Cognito User Pool is configured for the users to use their "email address" to sign up and sign in.
If a user signs up with the email of someone else then that email will get stuck in UNCONFIRMED state and the owner will not be able to use it appropriately.
Having said that let me provide an example with the following scenario:
User signs in with an email address the user doesn't own, let's say it is In this step (registration form) some more data is sent like organization name, and user full name.
Verification code is sent to the email
Now the user that owns wants to create an account (maybe some days in the future), so he goes and fills the registration form but an error is thrown by cognito {"__type":"UsernameExistsException","message":"An account with the given email already exists."}
Thinks to consider:
* If the email already exists but is in unconfirmed state then provide the user the option to resend the link. This option is not optimal because additional data might be already in the user profile as the 1st step exemplifies.
* A custom lambda can be done to delete the unconfirmed user before signup or as a maintenance process every day, but I am not sure if this is the best approach.
There is also this configuration under Policies in cognito consol: "How quickly should user accounts created by administrators expire if not used?", but as he name implies this setting will only apply to users if they are invited by admins.
Is there a proper solution for this predicament?
Amazon Cognito has provided pre-signup triggers for these functionality and auto signup also.Your thought is the same way as i have implemented that according to the cognito documentations.
Here I am using the amplify/cli which is the toolchain for my development purpose hence the lambda function used in the trigger is as below:
"use strict";
console.log("Loading function");
var AWS = require("aws-sdk"),
uuid = require("uuid");
var cognitoIdentityServiceProvider = new AWS.CognitoIdentityServiceProvider();
exports.handler = (event, context, callback) => {
const modifiedEvent = event;
// check that we're acting on the right trigger
if (event.triggerSource === "PreSignUp_SignUp") {
var params = {
UserPoolId: event.userPoolId,
Username: event.userName
cognitoIdentityServiceProvider.adminGetUser(params, function(err, data) {
if (err) {
console.log(err, err.stack);
} // an error occurred
else {
console.log("cognito service", data);
if (data.UserStatus == "UNCONFIRMED") {
cognitoIdentityServiceProvider.adminDeleteUser(params, function(
) {
if (err) console.log(err, err.stack);
// an error occurred
else console.log("Unconfirmed user delete successful ");
// successful response
// successful response
// Throw an error if invoked from the wrong trigger
callback('Misconfigured Cognito Trigger '+ event.triggerSource);
this will actually check and delete if the status is UNCONFIRMED using the aws-sdk methods adminGetUser and adminDeleteUser
hope this will help ;)
I got around this by setting ForceAliasCreation=True. This would allow the real email owner to confirm their account. The draw back is that you end up with 2 users. One CONFIRMED user and another UNCONFIRMED user.
To clean this up, I have a lambda function that calls list-users with filter for unconfirmed user and delete the accounts which were created before a certain period. This function is triggered daily by CloudWatch.
change to confirm from unconfirm:
aws cognito-idp admin-confirm-sign-up \
--user-pool-id %aws_user_pools_web_client_id% \
--username %email_address%

Email only authentication with Vue.js and Vuex on Firebase

I want user to be automatically authenticated (temporarily) on Firebase just by sending Email then be redirected to a welcome page asking to complete the auth process by following a link received by email.
The first part is ok, I can authenticate by just inserting email and generating a random password like the following (Vuex store action):
this.$store.dispatch('userSignUp', { email:, password: this.generatePassword })
which is called by component method button v-on:click="userSignUp
Vuex action is like :
userSignUp ({commit}, payload) {
commit('setLoading', true)
firebase.auth().createUserWithEmailAndPassword(, payload.password)
.then(firebaseUser => {
commit('setUser', firebaseUser)
commit('setLoading', false)
commit('setError', null)
.catch(error => {
commit('setError', error.message)
commit('setLoading', false)
So far so good, the user put the email, an helper function this.generatePassword generate a random password and the user is logged in and created on firebase.
Now this user is logged in, is on a welcome page, but it doesn't know his own random password (because I don't want to).
I want this to be one shot login and if the user want to come back, has to follow the link sent by email by Firebase.
There is a firebase function [sendPasswordResetEmail][1], which seems right for the case but I connot find the way to make it working.
I did Vuex action like before :
export const actions = {
sendPasswordReset ({commit}, payload) {
commit('setLoading', true)
.then(firebaseUser => {
commit('setUser', firebaseUser)
commit('setLoading', false)
commit('setError', null)
.catch(error => {
commit('setError', error.message)
commit('setLoading', false)
which is called by component method button v-on:click="userSignUp
methods: {
userSignUp () {
this.$store.dispatch('userSignUp', { email:, password: this.generatePassword })
this.$store.dispatch('sendPasswordReset', { email: })
I only get response code
"error": {
"errors": [
"domain": "global",
"reason": "invalid",
"message": "EMAIL_NOT_FOUND"
"code": 400,
"message": "EMAIL_NOT_FOUND"
while the Request Payload seems ok anyway :
{requestType: "PASSWORD_RESET", email: ""}
Any idea ?
The provider you're using is called the password provider. As its name implies it is heavily dependent on the user having (and knowing) a password. Since you are looking for passwordless authentication, I'd recommend against using the email+password provider as the basis.
Instead consider implementing a custom authentication provider. While this involves a few more components, it is not as difficult as you may think. You'll need to run trusted code, which you can do either on a server you already have, or on Cloud Functions. In either of those cases, you'll use one of the Admin SDKs to implement the sensitive parts of the authentication flow.
A quick list of steps that I think you'll need:
Create an endpoint (e.g. a HTTP triggered Cloud Function) for the user to request an authentication email.
Implement the code for this endpoint to:
Generate a random one-time code in there, which you're going to send to the user. Firebase Authentication calls this the out-of-band (or OOB) code, since it's sent to the user on a different medium than your app.
Store this code and the user's email address somewhere where only your server-side code can read it, e.g. in the Firebase Database or Cloud Firestore.
Send an email to the user, with the code or a link to a page that includes the code and their email address.
Create an endpoint (e.g. again a HTTP function, or web page) where the user enters (e.g. by clicking on a link in the email) the OOB code and their email address.
Compare the code the user entered, to the one you stored before.
If the codes match, generate a custom token for the user and send it to them.
The user/app now signs into Firebase with the custom token.

auth0 - email verification - user account does not exist or verification code is invalid

Here is my problem : In auth0 dashboard, I select a user within my users list and click on send a verification email... The user receive the mail, click on the link and get an error "User account doesn't exist or verification code is invalid" But the user exists and I do not use passwordless or sms authentication , my users have to enter their password and are also stored in mongodb. Any ideas to solve this?
-- edited precision added --
I'am actually using a customDB and here is my getUser script, but I don't know what to change, could you help me?
Thank you!
function getByEmail (email, callback) {
mongo('mongodb://', function (db) {
var users = db.collection('user');
users.findOne({ email: email }, function (err, user) {
if (err) return callback(new Error("my error message"));
if (!user) return callback(null);
var profile = {
user_id: user._id,
nickname: user.username,
callback(null, profile);
Ok, just re-read your question - where you state "my users have to enter their password and are also stored in mongodb." - are you referring to your own Mongo DB? Are you using an Auth0 Custom DB Connection? Confusingly, Auth0 also uses MongoDB for its own DB storage, hence the clarification. If you are using a Custom DB connection to your own DB, then this may be a misconfiguration of one of your Custom DB Scripts. If using Custom DB Script, please double-check the implementation of your GetUser.js script.
In the event, you are using an Auth0 DB (not a custom DB) then definitely check with Auth0 support team (as per comment and your reply above).

Parse-server: Reset Password

I am trying to implement my own local parse-server with my application. Everything is working fine except for reseting password for users.
I receive the following error
(node:8729) UnhandledPromiseRejectionWarning: Unhandledpromiserejection
(rejection id: 2): Error: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>404 Not Found</title><h1>Not Found</h1><p>The requested URL was not found on
the server.</p>
<p>If you entered the URL manually please check your spelling and try again.</p>
Do you have the email adapter configured in index.js? As per documentation,
Email verification and password reset
Verifying user email addresses and enabling password reset via email requires an email adapter. As part of the parse-server package we provide an adapter for sending email through Mailgun. To use it, sign up for Mailgun, and add this to your initialization code:
var server = ParseServer({
// Your apps name. This will appear in the subject and body of the emails that are sent.
appName: 'Parse App',
// The email adapter
emailAdapter: {
module: 'parse-server-simple-mailgun-adapter',
options: {
// The address that your emails come from
fromAddress: '',
// Your domain from
domain: '',
// Your API key from
apiKey: 'key-mykey',
