This plugin will limit access to the site. Only visitors with a cookie token will be able to access the public website. Visitors without the cookie will see a “coming soon” style of page.
You can customise the “coming soon” content, and you can change the way tokens work. Visit yoursite.com/?add_token to receive the token allowing you to see the site. To remove the limited access, simply disable this plugin.
By default, the token is “letmein”. So use these links: 
site.com?letmein 
site.com?takemeoff
This plugin is useful when you’re developing your site. You can work on your live web server without having your site open to the public.

Token Access

Limit access to the site to those with a cookie token.  Visitors without the cookie see a customisable "coming soon" style of page.

Share a link to anonymous users to preview a draft of a post (or any other public post type) before it is published.
Have you ever been writing a post with the help of someone who does not have access to your site and needed to give them the ability to preview it before publishing? This plugin takes care of that by generating an URL with an expiring nonce that can be given out for public preview.
Previously this plugin was maintained by <a href="https://profiles.wordpress.org/sivel/" rel="nofollow ugc">Matt Martz</a> and was an idea of <a href="https://profiles.wordpress.org/jdingman/" rel="nofollow ugc">Jonathan Dingman</a>.

<h3>Usage</h3>
<ul>
<li>To enable a public post preview check the box in the document settings. In the classic editor it’s in the “Publish” meta box.</li>
<li>The link will be displayed if the checkbox is checked, you can copy and share the link with your friends.</li>
<li>To disable a preview uncheck the box again.</li>
</ul>

Public Post Preview

This is one of the very few plugins I install on literally every single site I work on. Absolutely invaluable.
