Supported Email Gateways
The plugin uses the default WordPress email sending function ( wp_mail ). This means you are free to use any email service you want—whether it’s your web host’s built-in mail, your WordPress site’s configured SMTP settings, or a third-party SMTP plugin. Just configure your preferred email service, and OTP emails will be sent using that method.
You can also fully customize the OTP email: set a custom sender name, sender address, subject, and modify the email template as HTML directly from the plugin settings.
Additionally, you can add any other SMS gateway via WordPress hooks and filters.
