It is resolved using nodemailer-smtp-transport module inside createTransport   var smtpTransport   require  nodemailer-smtp-transport     var transport   nodemailer createTransport smtpTransport       service   gmail       auth            user           gmail com           pass        password

I found the simplest method  described in this article mentioned in Greg T s answer  was to create an App Password which is available after turning on 2FA for the account   myaccount google com   Sign-in  amp  security   Signing in to Google   App Passwords  This gives you an alternative password for the account  then you just configure nodemailer as a normal SMTP service   var smtpTransport   nodemailer createTransport       host   smtp gmail com       port  587      auth            user   username gmail com           pass   app password              While Google recommend Oauth2 as the best option  this method is easy and hasn t been mentioned in this question yet   Extra tip  I also found you can add your app name to the  from  address and GMail does not replace it with just the account email like it does if you try to use another address  ie    from   My Pro App Name  lt username gmail com gt

You should use an XOAuth2 token to connect to Gmail  No worries  Nodemailer already knows about that   var smtpTransport   nodemailer createTransport  SMTP         service   Gmail       auth          XOAuth2            user  smtpConfig user          clientId  smtpConfig client id          clientSecret  smtpConfig client secret          refreshToken  smtpConfig refresh token          accessToken  smtpConfig access token          timeout  smtpConfig access timeout - Date now                        You ll need to go to the Google Cloud Console to register your app  Then you need to retrieve access tokens for the accounts you wish to use  You can use passportjs for that   Here s how it looks in my code   var passport   require  passport        GoogleStrategy   require    google oauth2        config   require     config     passport use  google-imap   new GoogleStrategy     clientID  config  google api client id      clientSecret  config  google api client secret      function  accessToken  refreshToken  profile  done      console log accessToken  refreshToken  profile     done null        access token  accessToken      refresh token  refreshToken      profile  profile             exports mount   function  app      app get   add-imap  address    function  req  res  next        passport authorize  google-imap             scope               https   mail google com               https   www googleapis com auth userinfo email                     callbackURL  config  web vhost       add-imap           accessType   offline           approvalPrompt   force           loginHint  req params address          req  res  function              res send req user

See nodemailer s official guide to connecting Gmail   https   community nodemailer com using-gmail   -  It works for me after doing this    Enable less secure apps - https   www google com settings security lesssecureapps Disable Captcha temporarily so you can connect the new device server - https   accounts google com b 0 displayunlockcaptcha

Just attend those   1- Gmail authentication for allow low level emails does not accept before you restart your client browser 2- If you want to send email with nodemailer and you wouldnt like to use xouath2 protocol there you should write as secureconnection false like below  const routes   require  express   Router    var nodemailer   require  nodemailer    var smtpTransport   require  nodemailer-smtp-transport       routes get   test    req  res    gt      res status 200  json   message   test            routes post   Email    req  res    gt        var smtpTransport   nodemailer createTransport           host   smtp gmail com           secureConnection  false          port  587          requiresAuth  true          domains    gmail com    googlemail com            auth                user   your gmail account                pass   your password                      var mailOptions           from   from gmail com         to  to gmail com         subject  req body subject          text  req body content        html    lt p gt   req body content    lt  p gt           smtpTransport sendMail mailOptions   error  info    gt        if  error            return console log  Error while sending mail      error         else           console log  Message sent   s   info messageId             smtpTransport close               module exports   routes

Try disabling captchas in your gmail account  probably being triggered based on IP address of requestor  See  How to use GMail as a free SMTP server and overcome captcha

Same problem happened to me too  I tested my system on localhost then deployed to the server  which is located at different country  then when I try the system on production server I saw this error  I tried these to fix it    https   www google com settings security lesssecureapps Enabled it but it was not my solution https   g co allowaccess I allowed access from outside for a limited time and this solved my problem

Non of the above solutions worked for me  I used the code that exists in the documentation of NodeMailer  It looks like this   let transporter   nodemailer createTransport       host   smtp gmail com       port  465      secure  true      auth            type   OAuth2           user   user example com           serviceClient   113600000000000000000           privateKey   -----BEGIN PRIVATE KEY----- nMIIEvgIBADANBg              accessToken   ya29 Xx XX0xxxxx-xX0X0XxXXxXxXXXxX0x           expires  1484314697598
