By default, WordPress displays your username publicly as the author of your posts. This can, however, pose a security issue because you’re giving everyone your blog’s username login info. Also, it’s best to use a username that is not easily guessed which typically means you won’t be using your name.
So let’s change how WordPress displays your name to the world but at the same time not give out what your blog’s username is.
Follow The Guided Tutorial
When you install WordPress for the first time, you must either provide a Username in order to log into your WordPress account or one will be assigned to you automatically (i.e. the admin Username). If you host with WpBlogHost and install WordPress on your web hosting account, you can specify your own unique Username.
When you author a post or comment in your blog’s comment section, by default WordPress displays your Username as the author’s name (see the image above, left side).
This tutorial will show you how to change that so the name you want to display will be shown.
Step 1 – Find Users
Log into WordPress and in the left sidebar menu click on Users.
Step 2 – Edit User
On the right you should see a list of the Users for your blog. Move your mouse to the one you want to edit and when the menu shows, click Edit.
Step 3 – Choose Your Display Name
Scroll down until you see Display name publicly as and choose how you want your name to be shown in posts and comments.
Step 4 – Click Update User
Congratulations, you’ve changed your User display name.
