Smtp error could not authenticate gmail

I’m using PHPMailer in a Simple Script For Send Email’s Through Gmail, and I’m getting an «Unknown Error» (At least for me!):

SMTP Error: Could not authenticate.
Error: SMTP Error: Could not
authenticate.

SMTP server error: 5.7.1 Username and
Password not accepted. Learn more at

I’ve read about Configure OpenSSL For SSL/TLS Connections, and I did it. Apache And PHP Are properly-Configured (With OpenSSL extension Running in PHP and mod_ssl running in Apache 2.2.16).

This is The PHP Script:

 <?php
  require_once ("PHPMailerclass.phpmailer.php");
  $Correo = new PHPMailer();
  $Correo->IsSMTP();
  $Correo->SMTPAuth = true;
  $Correo->SMTPSecure = "tls";
  $Correo->Host = "smtp.gmail.com";
  $Correo->Port = 587;
  $Correo->UserName = "foo@gmail.com";
  $Correo->Password = "gmailpassword";
  $Correo->SetFrom('foo@gmail.com','De Yo');
  $Correo->FromName = "From";
  $Correo->AddAddress("bar@hotmail.com");
  $Correo->Subject = "Prueba con PHPMailer";
  $Correo->Body = "<H3>Bienvenido! Esto Funciona!</H3>";
  $Correo->IsHTML (true);
  if (!$Correo->Send())
  {
    echo "Error: $Correo->ErrorInfo";
  }
  else
  {
    echo "Message Sent!";
  }
?>

The Username and Password are OK, And I tried in Thunderbird, without any problem.
I’ve also Used SSL Authentication and Port 465, getting the same Error.

I received this error because of percentage signs in the password.

For me I had a special characters in my password field, and I put it like $mail->Password = » por$ch3″ which work for gmail smpt server but not for other; so I just changed double quotes to single quotes and it works for me. $mail->Password = ‘ por$ch3’;

1. first go to https://myaccount.google.com
2. Select Security tab
3. Scroll down and select ‘Less secure app access’
4. Turn on access

This will solve my “SMTP Error: Could not authenticate” in PHPMailer error.

I had the same issue and did all the tips with no luck. Finally when I changed password to something different, for some reason it worked! (the initial password or the new one did not have any special characters)

It was the selinux issue. I just updated the below given part in /etc/selinux/config file
SELINUX=permissive (it was SELINUX=enforcing before).
then just reboot the system by giving
reboot
Now the mail goes without any hassle.
Configuration

From Email Address : [noreply@yourdomain.com]
From Name : [your domain name]
SMTP Host   : smtp.gmail.com
Type of Encryption : SSL
SMTP Port : 465
SMTP Authentication  : YES
Username : [your mail id]
Password : [your password]

SMTP Error: could not authenticate
I had the same problem. The following troubleshooting steps helped me.

• I turned off two-factor authentication in my gmail account.
• I allowed less secure apps to access my gmail account. To get it working, I had to go to myaccount.google.com -> Sign-in & security -> Apps with account access, and turn Allow less secure apps to ON (near the bottom of the page).
• At this step, when I tried to register a user, I would get the same error. Google would sent me a warning message that someone has my password and the login was blocked.
• Gmail will then provide you with options. You either click whether the activity was yours or not yours. Click the option that the activity was yours.
• Try registration again. It should now work.

There is no issue with your code.

Follow below two simple steps to send emails from phpmailer.

• You have to disable 2-step verification setting for google account if you have enabled.

• Turn ON allow access to less secure app.

Добрый день всем

у меня случилась грабля — отправляется почта но не на все ящики, точнее почти на все не отправляется, кроме некоторых моих.
раньше отправка была через php mail — на мои ящики приходило — а заказчик пишет что не может зарегиться — не приходит письмо
перепробовал все, Joomla 3.3
даже решил через smtp для яндекса — теперь выскакивает ошибка подключения
сейчас настройки для сервера следующие

отправка почты — Да
способ — smtp
email: имя@yandex.ru
отправитель: ИМЯ
авторизация: Да
защита: TLS
порт: 465
имя пользователя: имя
пароль: ***
server: smtp.yandex.ru

где то вскользь видел, что проблемы могут на стороне хостера — но не понимаю в чем они могут быть
не работает ни один способ отправки
хостер 1gb

нашел статейку, попробовал

Решение проблем связанных с отправкой почты в Joomla и VirtueMart

почта отправляется и приходит
значит mail() работает — там далее описано как править файл

После этого если письмо не дошло нужно подправить файл Joomla отвечающий за отправку почты. Открываем файл librariesphpmailerphpmailer.php находим примерно в 472 строке след. участок кода

проблема в том что это описание для старой Joomla — в новой все подругому

причем самое паскудное, что регистрация через mail() приходит только на мои пару ящиков
вот это ваще мистика
 то есть она ходит на мой gmail на мой mail

а на все остальные не ходит — эт ваще пипец какой то
мож конечно она работает через локальный комп на котором денвер стоит…

Дабы не создавать новые темы.спрошу здесь.Joomla стоит на локальном сервере.Настроил почту через Gmail. В настройках Gmail Установите переключатель Включить IMAP. Сделал.
В Joomla всё прописал по инструкции.При попытке отправить тестовое сообщение выводится ошибка.  SMTP Error: Could not authenticate.
Помогите разобраться пожалуйста.
