Introduction
WordPress—and by extension BuddyBoss—does not allow editing the user_login field once an account is created. Changing a username requires custom intervention or a specialized plugin, as it isn’t available via the standard user-edit screen.
Options for Changing Usernames

Install a dedicated plugin (for example, Username Changer) that safely updates the user_login in the database without manual queries.
