sudo (Super User Do) allows us to execute the system commands with root privileges. Whenever you execute any command in the terminal with sudo it will ask you to enter your account password. This is added as a prefix to the commands that only superusers can run and are executed with proper authentication. But there is a way for running the sudo commands without the root account password, it is only recommended if you are the only user on your system otherwise it will risk your Linux Mint security.
