Show us your code. It's most likely "Allow less secure apps" or Captcha — Bergur, Aug 23 '18 at 08:31

You might need to allow access to your Gmail account.

https://accounts.google.com/b/0/DisplayUnlockCaptcha

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.

I tried this solution. It works for some hours. But gmail again starts blocking mail sending requests. – Nikhil Dec 04 '19 at 04:52
@Nikhil are you trying to send a large number of emails? – Shanil Arjuna Dec 15 '19 at 03:20
@RohitParte Great :) – Shanil Arjuna Dec 17 '19 at 09:32
@shanil-arjuna nope. Just one email. I finally decided to move to Amazon SES SMTP. I verified by GMail address under SES and started sending emails through Lambda without any issues. – Nikhil Dec 21 '19 at 15:27
@Nikhil Great :) – Shanil Arjuna Dec 22 '19 at 15:37
the low security methode was temporary and i couldn't use it in production but I found an article that made it easier using OAuth [here](http://blog.bessam.engineer/How-to-use-nodemailer-with-GMail-and-OAuth) – bessam Sahli Sep 06 '20 at 18:10

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.

This worked for me as well. No matter what I tired prior, google did not like my password while running my app on my live host. My local host was perfectly fine. Not until I followed this process, its now working in both my local and live environments. Many thanks! – klewis May 21 '21 at 18:52

Most of the time, this occurs only because of two major issues

I yet to enable the less secure option in google account under security
You should allow the google account to be accessed by the third party application. See https://accounts.google.com/DisplayUnlockCaptcha

I got the same issue as this works fine using postman client on local environment.

But giving the error or aws-linux vpc i configured.

So this can be fixed as:

let nodemailer = require('nodemailer');
const transporter = nodemailer.createTransport({
host: 'smtp.gmail.com',
port: 587,
ignoreTLS: false,
secure: false,
auth: {
    user: "your mail",
    pass: 'your password'
}
});
module.exports = transporter;

Please make sure you have allow access to your account and less secure apps setting should be turned on.

You just have to open the below link and enable to allow your google account access.

https://accounts.google.com/b/0/DisplayUnlockCaptcha

This will allow Google to complete this additional step when signing into a new device or application.

For gmail, you need to allow 2 step authorisation and then set up a 16 digit app password. Use that password with your gmail address, - not your regular password. Should be good to go!
