   etc. the invoice generated with Adobe Acrobat.

 * Add below filter to your themes functions.php in order to set protection. You
   can even set passwords. Check [here](https://mpdf.github.io/reference/mpdf-functions/setprotection.html).
 *     ```
       function bewpi_mpdf( $mpdf ) {
           // Encrypt the file and grant no permissions to the user to copy, print etc.
           // The user will be able to open the file as no password is specified
           // Owner cannot access full rights because no owner_password was set
           $mpdf->SetProtection(array());
   
           return $mpdf;
       }
       add_filter( 'bewpi_mpdf', 'bewpi_mpdf' );
       ```
