Eu estou aprendendo como enviar um email com javamail API, eu criei as propriedades necessárias e instruções para enviar um email simples usando o servidor SMTP e estou usando este código:

     Properties props=new Properties();
    props.put("mail.smtp.host", "smtp.gmail.com");
    props.put("mail.smtp.socketFactory.port", "465");
    props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.port", "465");

    Session session= Session.getDefaultInstance(props, new javax.mail.Authenticator() {

    protected PasswordAuthentication getpPasswordAuthentication(){
    return new  PasswordAuthentication("[email protected]", "password");
    }


    });
    try{
        Message message=new MimeMessage(session);
        message.setFrom(new InternetAddress("myemail"));    
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("recepientemailadresse"));
        message.setSubject("the java mail test");
        message.setText("Guess what brother the java mail is working correctly");
        Transport.send(message);
         JOptionPane.showMessageDialog(rootPane, "message sent");
    }
    catch(Exception e){
        JOptionPane.showMessageDialog(rootPane, e);
         e.printStackTrace();
    }

e no tempo de execução ocorreu uma exceção mencionando que:

    javax.mail.AuthenticationFailedException: failed to connect, no password specified?
