SMTP Auth (by PHPMailer) is a security process that authenticates your identity with an outgoing mail server before sending emails. By providing a valid username and password, it proves you're authorized to use the service, preventing unauthorized relay and ensuring your messages from web forms, notifications, or scripts are delivered reliably through trusted providers like Gmail, SendGrid, or your hosting company's SMTP server.
