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: {
                 


        

Answer 1

There are some account settings that are necessary for you to send through it using SMTP.

If you have two-step verification enabled on the account, you will need to use an application specific password (created in the Gmail account) in the device settings: Signing in using application-specific passwords

If not, please try this: sign into the Gmail account using a web browser at https://mail.google.com, then go to Settings > Accounts and Import > Other Google Account settings. Under Security, scroll down and enable access for less secure apps. This setting is required to enable SMTP, POP or IMAP access.

If there is still a problem, try clearing Captcha: visit https://accounts.google.com/DisplayUnlockCaptcha and sign in with the Gmail username and password. If necessary (it's usually not), enter the letters in the distorted picture then press Continue. This will allow ten minutes for the device to register as an approved connection. Note that you must use the account you are trying to add to the device - if the browser is already signed into another account, you must sign out first. Also, you must trigger the device to make a connection within ten minutes of pressing Continue.
