Change WordPress Username

The Username Change option lets you rename any WordPress user from the user edit screen. WordPress core grays out the username field on purpose. This module adds a "Change" link beside it so you can edit the value without touching the database.

Requirements

• WP Adminify 3.7 or higher (free or Pro).
• A user role with the edit_users capability. That's Administrator on a single site, Super Admin on Multisite.

Step 1 - Enable the Username Change option

1. In your WordPress admin, go to WP Adminify → Security.
2. Find the Users Security row and switch it to Show.
3. Toggle Username Change to Yes.

The setting saves on toggle. You don't need to reload the page.

Step 2 - Open the user you want to rename

1. Go to Users → All Users.
2. Hover over the user and click Edit. To rename your own account, click Profile in the admin sidebar instead.
3. Scroll to the Name section.

Step 3 - Change the username

1. Beside the Username field, click the Change link.
2. A New Username input appears below the current username.
3. Type the new username.
4. Click Save Change.

The username updates right away.

What happens after the change

• If you renamed your own account: WordPress logs you out. Log back in with the new username and your existing password.
• If you renamed another user: they get logged out the next time their session is validated. They must use the new username to log back in.
• The user ID, password, email, role, and authored content stay the same.
• The author archive URL changes from /author/oldname/ to /author/newname/.

Validation rules

WP Adminify checks the new username before saving:

• Must be unique. Duplicates are rejected.
• Allowed characters: letters, numbers, underscores, hyphens, periods, spaces, and the @ symbol.
• WordPress's sanitize_user() function strips invalid characters before save.
• Empty values are rejected.

Troubleshooting

The Change link does not appear

Check that Users Security is set to Show and Username Change is set to Yes under WP Adminify → Security. Clear your browser cache and reload the user edit screen.

"Username already exists" error

Pick a different username. WordPress requires every user_login value to be unique across the install.

Locked out after renaming your own account

Log in with the new username and your existing password. The password doesn't change. If you forgot the new username, ask another administrator to look it up under Users → All Users, or check the wp_users table in your database.

The public byline still shows the old name

The public byline is the Display name publicly as setting, not the username. Update it under Users → Profile.

Multisite

On WordPress Multisite, users live in the network-level wp_users table. Enable Username Change from the Network Admin and the rename applies across every subsite the user has access to.

Disabling the feature

To remove the Change link from user edit screens, go to WP Adminify → Security and toggle Username Change back to No. Already-renamed users keep their new usernames.
