Info

Changing the root password in Linux is easy, though it requires you to venture into the dark realm of the command line. Do note that anyone who has access to your computer can use this method to reset your superuser or root password. One precaution you can take is to encrypt the whole hard disk so it can’t be booted or mounted so easily.
