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.
