I've a PHP page that sends email upon submission. It was working fine but 2 days ago, it threw this message:
SMTP Error: Could not authenticate. Mailer Error: SMTP Error: Could not authenticate.
My code is as follow:
$host = "smtp.gmail.com";
$port = 465;
$secure_comm = "ssl";
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->IsHTML(true);
$mail->Host = $host;
$mail->Port = $port;
$mail->SMTPAuth = true;
$mail->SMTPSecure = $secure_comm;
$mail->Username = $email_user;
$mail->Password = $email_password;
$mail->From = $email_user;
$mail->FromName = $from;
$mail->AddAddress($to);
$mail->Subject = $email_subject;
$mail->Body = $message;
if(!$mail->Send())
echo "Mailer Error: " . $mail->ErrorInfo;
else
{
// Do something
}
I am using PHP 8.0 & PHPMailer 5.2.0. I've also enabled "Allow less secure apps" on Google admin console. The login credentials are also correct.
Any help?
Go to your Google account, turn on 2-step verification, create an app password, and then use that password in PHPMailer instead of your Gmail password. After that, try sending the email again.
