Nodemailer not loggin in

Question

I want to send an email from node backend and I am using the nodemailer library for express to achieve that. I have written the following code to configure the transport and other details for nodemailer

                let transport = nodemailer.createTransport({
                  host: 'mail.myrandomhost.in',
                  port: 587,
                  tls: {
                    rejectUnauthorized:false
                },
                  secure: false,
                  auth: {
                     user: 'me@myemail.in',
                     pass: 'Gr3aseMonk3y'
                  }
              });

              const message = {
                from: 'me@myemail.in',
                to: 'youremail@gmail.com',
                subject: 'test email',
                html: '<h1>Hey</h1><p>This is test <b>Tesla</b> email</p>'
            };
            transport.sendMail(message, function(err, info) {
                if (err) {
                  console.log('-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=');
                  console.log("FAILED");
                  console.log('=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-');
                  console.log(err)
                } else {
                  console.log('====================================');
                  console.log("Email sent");
                  console.log('====================================');
                  console.log(info);
                }
            });

When I run this, I get the following error

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
FAILED
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Error: Invalid login: 535 Incorrect authentication data

}

I am using the correct details. How do I solve this?

You entered the wrong data. you must change host , from to real addresses. Example:

let transport = nodemailer.createTransport({
                  host: 'smtp.gmail.com',
                  port: 465,
                  tls: {
                    rejectUnauthorized:true
                },
                  secure: false,
                  auth: {
                     user: 'yourRealEmail@gmail.com',
                     pass: 'yourPassword'
                  }
              });

              const message = {
                from: 'yourRealEmail@gmail.com',
                to: 'RealEmailAddress@gmail.com',
                subject: 'test email',
                html: '<h1>Hey</h1><p>This is test <b>Tesla</b> email</p>'
            };
            transport.sendMail(message, function(err, info) {
                if (err) {
                  console.log('-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=');
                  console.log("FAILED");
                  console.log('=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-');
                  console.log(err)
                } else {
                  console.log('====================================');
                  console.log("Email sent");
                  console.log('====================================');
                  console.log(info);
                }
            });
