The username in Linux is a fundamental part of each task since without a user it would be impossible to access the computer, be it a normal user, a user with administrative permissions or even the root user himself, hence the importance of the user in Linux . Having differentiated users when different people use the same computer is important to separate information, even if the same person uses the PC in different ways..
To have a well-managed team, having users configured correctly helps us to be able to use it effectively. In Ubuntu 20.04, 20.10 or Ubuntu 21.04 it is possible to change the username from the terminal and getFastAnswer will explain how to do it in a simple way using commands.

Step 8
In the system we open the terminal and access as root:

Step 12
In the terminal we delete the created user:
