At this time password protection is not available for standard Showit pages.
Password protection is only available for post or page content entered in WordPress. None of the content placed in a blog template within Showit can be password protected.
Set Up a Password Protected Blog Page
First you will need to Create a Page Template in order for your Showit blog theme to properly display a WordPress page. Content in your page template will not be protected.
Once your Page template is published you can then create a page in your blog by logging into your blog admin. Only the page content typed into the Wordpress page will be protected.
3. You can set Password Protection under the Publish > Visibility settings on the right sidebar. Then Publish.
