Who loves to see a website which is under construction? Probably – Nobody. At development stage, website should not be made public. So, how to hide the entire site from public viewing?
There is a plugin for that; Hide My Site. This plugin uses a single password to protect entire site from public view and search engine.
Install it. Then Set a Password from Settings of the plugin. You may also choose how many days your site will be password protected. There are other option for Brute Force Protection. But that is not necessary.
