Username and Password not accepted when using nodemailer?

问题

This is my settingController:

var sendSmtpMail = function (req,res) {
  var transport = nodemailer.createTransport({
  service:'gmail',
   auth: {
             user: "asdfqweerrccb@limitlesscircle.com",
             pass: "qwerr@wee"
        }
   });
   var mailOptions = {
        from: "transactions@limitlesscircle.com", 
        to:'umaraja1124@gmail.com', 
        subject: req.body.subject+"nodejs working ?", 
        text: "Hello world ?",  
    }
    transport.sendMail(mailOptions, function(error, response){
      if(error){
         res.send("Email could not sent due to error: "+error);
         console.log('Error');
       }else{
         res.send("Email has been sent successfully");
         console.log('mail sent');
      } 
  });

in postman I got the error like that:

Email could not sent due to error:

Error: Invalid login: 535-5.7.8 Username and Password not accepted. Learn more at 535 5.7.8  https://support.google.com/mail/?p=BadCredentials g7sm64435626pfj.29 - gsmtp

I think that first you need to Allow less secure apps to access account setting in your google account - by default this settings is off and you simply turn it on.

Then I use the following script to send emails from a gmail account, also tested with yahoo and hotmail accounts.

const nodemailer = require('nodemailer');

let transporter = nodemailer.createTransport({
    host: 'smtp.gmail.com',
    port: 587,
    secure: false,
    requireTLS: true,
    auth: {
        user: 'your.gmail.account@gmail.com',
        pass: 'your.password'
    }
});

let mailOptions = {
    from: 'your.gmail.account@gmail.com',
    to: 'receivers.email@domain.com',
    subject: 'Test',
    text: 'Hello World!'
};

transporter.sendMail(mailOptions, (error, info) => {
    if (error) {
        return console.log(error.message);
    }
    console.log('success');
});

If you put the previous code in send-email.js for example, open terminal and write:

node send-email

You should see in the console - success, if the email was send successfully or the error message returned by nodemailer

Don't forget to first do the setting - Allow less secure apps to access account.

I hope this code will be useful for you. Good Luck!

If you have enabled 2-factor authentication on your Google account you can't use your regular password to access Gmail programmatically. You need to generate an app-specific password and use that in place of your actual password.

Steps:

Log in to your Google account
Go to My Account > Sign-in & Security > App Passwords
(Sign in again to confirm it's you)
Scroll down to Select App (in the Password & sign-in method box) and choose Other (custom name)
Give this app password a name, e.g. "nodemailer"
Choose Generate
Copy the long generated password and paste it into your Node.js script instead of your actual Gmail password. (You don't need the spaces.)

Your script will now look like this:

var transporter = nodemailer.createTransport({
  service: 'gmail',
  auth: {
    user: 'YOUR-GMAIL-USERNAME@gmail.com',
    pass: 'YOUR-GENERATED-APP-PASSWORD'
  }
});

I hope this helps someone.

You are using gmail service so your mail must be in gmail:

var transport = nodemailer.createTransport({
service:'gmail',
 auth: {
             user: "asdfqweerrccb@gmail.com",
             pass: "qwerr@wee"
        }
    });
var mailOptions = {
        from: "transactions@gmail.com", 
        to:'umaraja1124@gmail.com', 
        subject: req.body.subject+"nodejs working ?", 
        text: "Hello world ?",  
    }
transport.sendMail(mailOptions, function(error, response){
    if(error){
         res.send("Email could not sent due to error: "+error);
         console.log('Error');
    }else{
         res.send("Email has been sent successfully");
         console.log('mail sent');
    } 
});

Make sure you are using the right port: ie port: 587 as of now.

Visit this link to allow Less secure App access: https://myaccount.google.com/lesssecureapps

Enable the recaptcha at this link: https://accounts.google.com/b/0/DisplayUnlockCaptcha

Wait for a few minutes and try to send an email.

Alternatively use sendgrid. It has a free version.

If you are not seeing the emails in your inbox, check the Spam folder.
