Describe the enhancement

Enhanced function: Add article password

Sometimes we don't want to show part of the web page to everyone, so we can encrypt our web page so that it can be accessed through a password. Similar to the following code, modify "your_site\layouts\posts\single.html", but it does not work for hugo-coder:

{{- $password := $params.password | default "" -}}
     {{- if ne $password "" -}}
         <script>
             (function(){
                 if({{ $password }}){
                     if (prompt('please enter password') != {{ $password }}){
                         alert('password error!');
                         if (history.length === 1) {
                             window.opener = null;
                             window.open('', '_self');
                             window.close();
                         } else {
                             history.back();
                         }
                     }
                 }
             })();
         </script>
     {{- end -}}
