Smart Protect is a plugin for WordPress, which allows us to protect our site with a password in an easy way. We just need to install it on our WordPress site, activate it and then go to the options, which are located on the left side panel of WordPress, there we will find an option with the name "Smart Protect", in it we can choose whether to enable or disable it, you can place the password with which you want to protect your site and also have the option to choose which pages within your WordPress will not be password protected. We will continue to improve and include new features for the plugin.
