What are the potential pitfalls of displaying sensitive information, such as passwords, in PHP email messages?

Displaying sensitive information, such as passwords, in PHP email messages can pose a security risk as email messages can be intercepted or accessed by unauthorized parties. To mitigate this risk, it is recommended to avoid including sensitive information like passwords in email messages. Instead, consider using secure methods for transmitting sensitive data, such as encrypted communication channels or secure APIs.

// Send the email
mail($to, $subject, $message, $headers);
