Answer 1

You might need to allow access to your Gmail account.

Edit (after your comment)

// create reusable transporter object using the default SMTP transport

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

your 'nodemailer.createTransport' should look something similar.

Answer 2

If you use GMAIL service as a transporter,

Step-1: Log in to your gmail account.

Step-2: Enable less secure app access and/or DisplayUnlockCaptcha on your gmail account.

Step-3: Follow a 6-step guide on Sign in with App Passwords

Step-4: Replace your transporter password with the 16-character generated app password you obtain from Step-3 above.

These four easy steps solved my problem.
