About
Change WordPress usernames from the user edit screen, with validation for existing users, illegal logins, and Multisite admins.
What It Does
Change Username adds a field to the WordPress user edit screen so administrators can rename a user's login directly, rather than going through the database or a custom script. It blocks changes that would conflict with existing usernames, reserved names, or Multisite super admin accounts, so the rename stays safe and reversible through the standard admin UI.
Who It's For
This plugin fits WordPress administrators who occasionally need to fix typos, rebrand a user account, or restructure usernames on a live site without touching phpMyAdmin. It is most useful on Multisite networks, membership platforms, and agency-managed client sites where users are created in volume and naming mistakes need to be corrected after the fact.
Who Should Skip It
If you only create a handful of accounts and rarely rename them, or if you are comfortable editing wp_users in the database, this plugin adds little value. Sites that already rely on a full identity management or SSO solution should skip it, since those tools govern usernames at a higher level.
The Bottom Line
Change Username does one thing and does it with current code, modern requirements, and a clean maintenance record, earning an overall 77.43 out of 100 from PluginCheck. The main caveat is the absence of any support thread history, so if you hit an edge case on Multisite you may be on your own. For administrators who need a safe, admin-screen way to rename users, it is a sensible, lightweight pick.
