外掛說明
Change WordPress usernames from the user edit screen, with validation for existing users, illegal logins, and Multisite admins.
Change Username
WordPress does not let administrators change usernames by default. Change Username adds that option directly to the existing user edit screen, without a separate settings page.
Use it to update a WordPress username while keeping the same user ID, posts, comments, and profile data attached to the account.
Features
- Change any WordPress username from the existing user edit screen.
- Prevent username conflicts by checking whether the new username already exists.
- Block usernames that are listed as illegal logins.
- Follow the same username validation rules as WordPress core.
- Retain superadmin rights when changing the username of a Multisite super admin.
Requirements
- PHP version 7.4 or higher
- WordPress version 6.0 or higher

常見問題集
-
Where do I change a WordPress username after activation?
-
Go to Users, open the user you want to edit, and use the username control on the existing user edit screen.
-
Can I change an administrator username?
-
Yes. Any user with the
edit_userscapability can change usernames, including administrator usernames. -
Can users change their own username?
-
Not right now. Only administrators with the
edit_userscapability can change usernames. -
Does changing a username affect user IDs or posts?
-
No. The plugin changes the user’s login name, but it does not change the user ID. Existing posts, pages, comments, and user metadata stay assigned to the same user account.
-
Does this work on WordPress Multisite?
-
Yes. When changing the username of a Multisite super admin, the plugin keeps that user in the super admin list.
-
I’ve activated the plugin but nothing happens.
-
Please check if your server is running PHP version 7.4 or higher. The plugin will not do anything if you’re on an older version of PHP.
