The WordPress Obscurity feature obscures certain WordPress settings from public view.
Note: Obscurity is not true security and so the following settings are down to your personal tastes.
The WordPress Obscurity options explanations
Option: Mask WordPress Version
This option prevents public display of your WordPress version.
Important: This may interfere with WordPress plugins that rely on the $wp_version variable.
Enter how you would like your WordPress version displayed publicly. Leave the field blank to disable this feature.
Option: WP Generator Tag
This option helps you to remove WP generator meta tag.
If you want to remove a meta tag from your WordPress pages that publicly displays that your site is WordPress and its current version, enable this option.
Option: Block Username Fishing
This option blocks the ability to discover WordPress usernames based on author IDs.
Important: Enabling this option may interfere with expected operations of your site.
If you want any URL requests containing "author=" to be killed, enable this option.
