In this tutorial, we will show you how to create and delete a user on Debian 9. In the initial server setup, there is only one user account created and that is “root” user account. This root user has the highest privileges and has access to all files and commands on the system. But having too many privileges and running as root user is not always recommended and if you are not careful enough it can have destructive consequences for your system.
That’s why it is recommended to create additional users with limited privileges for your most common tasks. A new user account should also be created for any other user that will be using your server. Additionally, we will also show you how to give those users root privileges when necessary through the sudo command.
