Introduction
Overview
In Ubuntu, the “root” user plays a critical role when performing system administration and essential configurations. One of those ‘different things’ is the concept of the root user.

What is root user?
When asked for password, enter your account’s password. But there’s more to root account in Ubuntu that you should know.
When you have just started using Linux, you’ll find many things that are different from Windows. This user account works as the admin on your system and as per the default sudo policy in Ubuntu, it can run any command on your system with root privileges.
The thing with sudo is that running sudo doesn’t require root password but the user’s own password.
And this is why when you run a command with sudo, it asks for the password of the user who is running the sudo command:
As you can see in the example above, user abhishek was trying to run the ‘apt update’ command with sudo and the system asked the password for abhishek.
If you are absolutely new to Linux, you might be surprised that when you start typing your password in the terminal, nothing happens on the screen.
