node.js email doesn't get sent with gmail smtp

Question

I'm trying to send the email gmail smtp but I'm getting the error:

My email and password is correct I'm using the nodemailer for sending the mail;

       var nodemailer = require('nodemailer');

                // create reusable transporter object using SMTP transport 
                var transporter = nodemailer.createTransport({
                    service: 'Gmail',
                    auth: {
                        admin: 'myuseremail.com',
                        pass: 'password'
                    }
                });

                var mailOptions = {
                    from: 'sender address', // sender address 
                    to: to, // list of receivers 
                    subject: 'Password Reset', // Subject line 
                    html: 'Your one time password is : <b>' + temporaryPassword + ' </b>' // html body 
                };

                transporter.sendMail(mailOptions, function (error, info) {
                    console.log(error,info);
              }

in log i'm getting the error:

    {
     [Error: Invalid login]
      code: 'EAUTH',
      response: '535-5.7.8 Username and Password not accepted. Learn more at\n535 5.7.8  https://support.google.com/mail/answer/14257 k5sm20957041pdo.48 - gsmtp',
      responseCode: 535

Answer 1

var transporter = nodemailer.createTransport({
  service: 'Gmail',
  auth: {
    user: 'user@gmail.com',
    pass: 'password'
  }
});

Try the above and also, do the following which was worked for me.

login in to https://www.google.com/settings/security/lesssecureapps and TURN ON Access for less secure apps.

I hope it will work for you too.

Thank you.

Answer 2

1. First of all, you have to enable the settings to allow less secure apps for the gmail account that you are using. Here is the link : https://myaccount.google.com/lesssecureapps

2. Secondly, Allow access for "Display Unlock captch option" (Allow access to your Google account). Here is the link : https://accounts.google.com/DisplayUnlockCaptcha

Answer 3

In case you're using OAuth2 and you're facing the issue above, configuring my transporter as shown below resolved my issue.

const transporter = nodemailer.createTransport({
  host: 'smtp.gmail.com',
  port: 465,
  secure: true,
  auth: {
    type: 'OAuth2',
    user: process.env.MAIL_USER,
    clientId: process.env.GOOGLE_CLIENT_ID,
    clientSecret: process.env.GOOGLE_CLIENT_SECRET,
    refreshToken: process.env.GOOGLE_CLIENT_REFRESH_TOKEN
  }
});

If you're unsure how to generate the id, secret and token, follow the steps here https://medium.com/@pandeysoni/nodemailer-service-in-node-js-using-smtp-and-xoauth2-7c638a39a37e
