javax.mail.AuthenticationFailedException Java Mail

Question

I have made a little program that send a message to my email account. Most of my code seems to work fine. However, I have encounter the AuthenticationFailedException when I am my code hit transport.send in my program. I am not sure why because I think I have everything set up correctly. Here is my code.

JavaEmail.java

public static void main (String[] args) throws Exception{
                //intialize logger 
protected static Logger logger = LogManager.getLogger(JavaEmail.class.getName());

//smtp related parameters 
private static String smtpUseremail;
private static String smtpReceiverEmailAddress;
private static String smtpUserpassword;
private static String smtpPortnumber;
private static String smtpHost;

private static String emailSubject;

//stack error message variable 
private static String message;

        try {

            logger.info("-----------------------------");
            logger.info("---------Starting up---------");
            logger.info("-----------------------------");

            initialize();

            String body = "This is a test";

            logger.info("Start to connect to email server");

            sendFromGmail(smtpUseremail, smtpUserpassword, smtpReceiverEmailAddress, emailSubject, body);



           // System.out.println("error message: " + message);

            logger.info("Email Sent");


        }
        catch (Exception e){
            logger.error(e);

            // message = e.toString();

            throw e;


        }
    }

    //Setting up Email Server
    private static void sendFromGmail(String from, String pass, String to, String subject, String body) {


        Properties props = PropertiesUtil.loadProperties("main.properties");

        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", smtpHost);
        props.put("mail.smtp.port", smtpPortnumber);

        Session session = Session.getInstance(props,
                  new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication(smtpUseremail, smtpUserpassword);
                    }
                  });

        MimeMessage message = new MimeMessage(session);



        try{


            message.setFrom(new InternetAddress(from));

            message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));


            message.setSubject(subject);

            message.setText(body);

            Transport.send(message);

            logger.info("Message has been delievered, check your mail");

        }

        catch (MessagingException e) {
            logger.error("Messaging Exception");

            throw new RuntimeException(e);
        }
    }


    //Initializing Properties
    private static void initialize() throws Exception  {

        Properties props = PropertiesUtil.loadProperties("main.properties");

        //smtp set up
        smtpPortnumber = props.getProperty("portNumber");
        smtpReceiverEmailAddress = props.getProperty("recipientEmailAddress");
        smtpUseremail = props.getProperty("userEmailAddress");
        smtpUserpassword = props.getProperty("userPassword");
        smtpHost = props.getProperty("emailHost");
        emailSubject = props.getProperty("");

    }

}

main.properties

portNumber = 465
recipientEmailAddress = [email protected]
userPassword = secert
userEmailAddress = [email protected]
emailHost = smtp.gmail.com

Also activating the Lesssecureapps

A link to a solution is welcome, but please ensure your answer is useful without it: add context around the link so your fellow users will have some idea what it is and why it’s there, then quote the most relevant part of the page you're linking to in case the target page is unavailable. Answers that are little more than a link may be deleted.

Activating displayUnlockCaptcha has done it for me.
