Our analysis

AI-assisted

SX User Name Security is a WordPress plugin designed to enhance user security by obscuring user login information. It modifies the Display Name and Nickname fields to prevent hackers from easily identifying user logins based on publicly visible information. The plugin also alters the body_class function to remove user IDs and nicenames from front-end pages.

This plugin is suitable for WordPress site owners who want to improve their site's security by ensuring that user information is not easily accessible to potential attackers. It is particularly useful for sites with multiple users or those concerned about user privacy.

Best for: WordPress site owners looking to enhance user privacy and security.

What it does well

  • Randomises Display Name and Nickname for security
  • Changes user information during registration
  • Available in French and English

Where it falls short

Verdict

SX User Name Security offers a straightforward solution for obscuring user information on WordPress sites. It is a useful tool for those prioritising security but may require additional steps for existing users.

From the developer

Daniel Roch's own description of SX User Name Security, lightly tidied.

WordPress show your WordPress login and ID in several places. It’s time to fix this !

  • WordPress automaticaly uses “User login” to fill in the “User Display Name”.
  • WordPress also allows everyone to use the same value for Nickname, Display Name and Login.
  • The body_class function also shows to everyone your User ID and Login on author pages.

A hacker can easily see then use your “NickName” or “Display Name” to find your real login. Once activated, SX User Name Security will prevent WordPress from showing those informations, and will warn you if you need to fix old users.

Features

Body_class function:

  • Removes User ID from body_class function (front-end users pages)
  • Removes User Nicename from body_class function (front-end users pages)

Current User informations:

  • The plugin changes “Display Name” and “Nickname” to a random value (like ‘Ticibe T. Aduvoguripe’, ‘Lagubo N. Agigerovibe’ or ‘Datela N. Orejadavino’) if they are identiqual to user login
  • If not, it changes “Display Name” to “Nickname” or “Nickname” to “Display Name” if one of them is identiqual to user login

New Registration:

  • Display Name and Nickname are changed to random value during user registration.
  • Nicename is also changed (it’s used to generate the user permalink on the front-end). For previous user, a notice has been added to use another plugin to safely change old nicenames.

Other information:

All functions are translated into french and english.
