Is there a work around google disabling "Less secure apps"?

Question

So since the 31 of may google has disabled the option for "Less secure apps", so I have been using the Java mail API, and since the update i can no longer send emails using the Gmail smtp.

This is the error I'm getting:

javax.mail.AuthenticationFailedException: 535-5.7.8 Username and Password not accepted. Learn more at
535 5.7.8  https://support.google.com/mail/?p=BadCredentials n13-20020a5d400d000000b0020ff7246934sm4970874wrp.95 - gsmtp

I switched to an outlook mail and it seems to work fine, but i was wondering if there is a way to use a Gmail account

Less secure apps & your Google Account

Answer 1

You could try authentification via "App password".

On your Google account:

1. set 2-Step Verification ON

2. create 16-character "App password"( How to create app password) -> result should be similar to: 16-character "App password"

3. Instead of Google account password use 16-character password

   MailMessage mail = new MailMessage();
   foreach (string receiver in DolociPrejemnike())
       mail.To.Add(receiver);
   mail.From = new MailAddress("[email protected]", "No replay"); //pošiljatelj (vedno enak)
   mail.Subject = SetSubject();
   mail.Body = SetBody();
   mail.IsBodyHtml = true;
   
   SmtpClient smtp = new SmtpClient();
   smtp.Host = "smtp.gmail.com";
   smtp.Port = 587;
   smtp.UseDefaultCredentials = true;
   smtp.Credentials = new System.Net.NetworkCredential("[email protected]", "xtqapucsmyvqmvxp"); // Enter seders User name and password  
   smtp.EnableSsl = true;
   smtp.Send(mail);
