One of the most basic tasks to that you should know how to do on a fresh Linux server is add and remove users. When you create a new server, you are only given the
root account by default.
While this gives you a lot of power and flexibility, it is also dangerous and can be destructive. It is almost always a better idea to add an additional, unprivileged user to do common tasks. You also should create additional accounts for any other users you may have on your system. Each user should have a different account.
You can still acquire administrator privileges when you need them through a mechanism called
sudo. In this guide we will cover how to create user accounts, assign sudo privileges, and delete users.
