This plugin solves two common frustrations with default WordPress user profiles:
<ol>
<li>Inability to Change Usernames: By default, a username cannot be changed after creation. This plugin adds a simple field for administrators to update any user’s username directly from their profile page.</li>
<li>Reliance on Gravatar: This plugin allows your users to set their own profile picture by selecting an image directly from the WordPress Media Library, giving them more control and overriding the default Gravatar. If no custom avatar is set, a clean placeholder image is used instead.</li>
</ol>
It’s a lightweight, secure, and easy-to-use solution for enhancing user management on your WordPress site.

Custom Default User Avatar is a fork of original <a href="https://wordpress.org/plugins/wp-user-avatar/">WP User Avatar</a> plugin. Since its original functionality was removed after a significant overhaul by the plugin author, this plugin continues the original direction from v2.2.16. This version also includes security fixes and patches as suggested by WordPress Plugins Team.
