Username and Password not accepted when using nodemailer?

Question

This is my settingController:

var sendSmtpMail = function (req,res) {   var transport = nodemailer.createTransport({   service:'gmail',    auth: {              user: "[email protected]",              pass: "qwerr@wee"         }    });    var mailOptions = {         from: "[email protected]",          to:'[email protected]',          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. Also you need to make sure that 2 factor authentication for the account is disabled. You can check how to disable it here.

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: '[email protected]',         pass: 'your.password'     } });  let mailOptions = {     from: '[email protected]',     to: '[email protected]',     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!
