and my code
$mail = new PHPMailer(); // create a new object
$mail->IsSMTP(); // enable SMTP
$mail->SMTPDebug = 1;
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'tls'; // secure transfer enabled REQUIRED for GMail
$mail->Host = "smtp.gmail.com";
$mail->Port = 587; // or 587
$mail->IsHTML(true);
$mail->Username = "googleaccount#gmail.com";
$mail->Password = "pass";
$mail->SetFrom("user#gmail.com");

Answer 1

enable "Access for less secure apps" :
https://www.google.com/settings/security/lesssecureapps

Answer 2

gmail does not allow to send emails from less secured applications. there is an option 'access for less secured apps' in google account settings. turn that on and you will be able to send emails.

Answer 3

i was facing same issue some days before . i found this solution , may be it works for you.Pass your values like this. its strange but worked for me.
$username="googleaccount#gmail.com";
$password="pass":
$mail->Username = $username;
$mail->Password = $password;
