Beskrywing
Changing usernames should be a pretty straightforward feature. Unfortunately, WordPress doesn’t allow it by default. Username Changer attempts to remedy that oversight.

Excellent Work! Great plugin, super simple and easy. Surprised this is not in the WP Core...

I like how easy it changes username.
Will be great if I could change user_nicename fields as well.
Had to use another plugin for this: https://ru.wordpress.org/plugins/edit-author-slug/
It's too complex, I only want to type manual value, without having to study complex settings page.

I used the gif file on the screenshots section of the main plugin page for help. That's all. I changed the admin-name. All posts are automatically assigned to the new user. Everything else, like e-mail address, password stays the same.

This plugin saved me the whole process of going to PHPmyadmin to make these username changes.
