I get a error "{ Error: Invalid login: 535-5.7.8 Username and Password not accepted." when I try send a mail with the module nodemailer from Node JS

Question

I am new in Node js and I try send a message like example to other e-mail and when I run the file in the terminal from linux I get this error:

root@me:/home/memee/Desktop/test/NodeJS/mail# nano example.js
root@me:/home/memee/Desktop/test/NodeJS/mail# node example.js

  responseCode: 535,
  command: 'AUTH PLAIN' }

I understand that my error is the login but my password and email is correct.

My code :

var nodemailer = require('nodemailer');

var transporter = nodemailer.createTransport({
  service: 'gmail',
  auth: {
    user: 'example@gmail.com',
    pass: 'here I put my password'
  }
});

var mailOptions = {
  from: 'from@gmail.com',
  to: 'to@gmail.com',
  subject: 'Sending Email using Node.js',
  text: 'That was easy!'
};

transporter.sendMail(mailOptions, function(error, info){
  if (error) {
    console.log(error);
  } else {
    console.log('Email sent: ' + info.response);
  }
});

my version of node and npm :

root@me:~# node --version
v8.11.3
root@me:~# npm --v
6.1.0
root@me:~#

Answer 1

I ran into this recently and it was related to the Less secure apps settings on the account.

Choosing "Allow users to manage their access to less secure apps" fixed it.

Answer 2

Turn on Allow less secure apps at https://www.google.com/settings/security/lesssecureapps

Answer 3

I'd the same problem earlier but after removing '@gmail.com' from username worked fine for me.
Error '535-5.7.8 Username and Password not accepted' occurs only in following mentioned cases:

1. Wrong credentials.
   
2. adding @gmail.com in the username, avoid it!
   
3. two-factor authentication enabled. If yes, then disable it.
   
4. https://myaccount.google.com/lesssecureapps if it is OFF, turn it ON to enable lesssecureapps.

Answer 4

your email and password are not matching, look at the error message: response: '535-5.7.8 Username and Password not accepted..

see this part of your code:

var transporter = nodemailer.createTransport({
  service: 'gmail',
  auth: {
    user: 'example@gmail.com', // here use your real email
    pass: 'here I put my password' // put your password correctly (not in this question please)
  }
});

If you make a login with your user and password, you will be able to send emails.

I used the same code to send this email, but with my credentials:

Answer 5

I tried this and worked for me:

#1 Create a google app password https://support.google.com/accounts/answer/185833

#2 Use:

host: "smtp.gmail.com",
port: 587,
auth: {
  user: "Your username here e.g:abc@gmail.com",
  pass: "Your password here"
}

Answer 6

Step1 However, you need to allow less secure apps from your google account to send emails. Through this link . Allow less secure apps From your Google Account

Read below instruction Enable imap

Short url for Enable IMAP in IMAP access section GO TO URL

const nodemailer = require("nodemailer");
let transporter = nodemailer.createTransport({
host: "smtp.gmail.com",
port: 587,
secure: false, // true for 465, false for other ports
type:"oauth2",
auth: {
  user: "myusernmae@gmail.com", // generated ethereal user
  pass: "Mypassword", // generated ethereal password
}});

transporter.verify(async function(error, success) {
if (error) {
  console.log(error);
} else {
  let info = await transporter.sendMail({
      from: '"Fred Foo " <foo@example.com>', // sender address
      to: "manoj@gmail.com, baz@example.com", // list of receivers
      subject: "Hello ✔", // Subject line
      text: "Hello world?", // plain text body
      html: "<b>Hello world?</b>", // html body
  });
  console.log(info);
  console.log("Server is ready to take our messages");
}});

Here is the complete solution to it. Cheers!!!

• Create reusable transporter object using the default SMTP transport

   transporter = nodemailer.createTransport({
    host: 'smtp.gmail.com',
    port: 465,
    secure: true, 
    auth: {
        user: 'yourEmail', //Remove '@gmail.com' from your username.
        pass: 'yourPassword' 
     }
   });
  

• Turn on Allow less secure apps at https://www.google.com/settings/security/lesssecureapps

• Allow Less secure app access : https://myaccount.google.com/lesssecureapps

• Done!!
