If you’re looking to add an extra layer of security to your WordPress site, there are a few code snippets you can add to your plugin to help make it more secure.

One way to add security to your plugin is to code it so that it can only be used by certain IP addresses. This way, only people who are allowed to access your site will be able to use the plugin.

Another way to add security to your plugin is to add a user authentication system. This way, only people who have the correct username and password will be able to use the plugin.

both of these methods will help to make your WordPress site more secure and less vulnerable to attack.
