SX User Name Security is a free WordPress plugin focused on improving user identity protection by masking sensitive information. It addresses common vulnerabilities within WordPress sites, ensuring that user logins and IDs are not easily exposed. By obscuring display names and nicknames, the plugin significantly reduces the risk of unauthorized access and potential targeted attacks. It modifies the body_class function to eliminate user IDs from front-end pages, offering an additional layer of security.

The plugin further enhances privacy during user registration by randomizing Display Names and Nicknames if they match the user login. Existing users can also modify these fields to bolster their privacy. SX User Name Security is available in both English and French, making it user-friendly for a wider audience. This plugin is an essential tool for WordPress site owners looking to enhance their site's security and protect user identities.
