Use Display Name instead of Username
By default, Buddypress uses the username for identification of the currently logged-in user on your website. Our Theme Developers added a settings where you can easily change this to show the user’s First Name and Last Name instead of their username to make it look more professional. Please follow the steps below.
Go to your Wordpress Admin Dashboard
Appearance - Theme Settings - Buddypress
Change the toggle to First Name & Last Name (refer to screenshot below)
