Are there best practices for securing sensitive information, such as usernames, when sending emails through PHPMailer?

When sending emails through PHPMailer, it is important to secure sensitive information such as usernames by using encryption methods like SSL or TLS. This can help prevent unauthorized access to the email content and protect user data. Additionally, it is recommended to store sensitive information in secure locations and avoid hardcoding credentials directly in the code. 

$mail = new PHPMailer(true);

$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your_username';
$mail->Password = 'your_password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

// Add email content and recipient
$mail->setFrom('from@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Subject';
$mail->Body = 'Email content';

$mail->send();
