In today’s tutorial, we will show you how to change the root password in Linux. The root account on a Linux machine is the highest authority account on the system. It has control over everything, can delete and modify anything, and has permission to run any program. Simply put, the root account can do anything that the system supports. Typically, casual users never need to use the root account, while more experienced users need the root account more often, especially if they spend a large amount of their time at a terminal.
