Kali Linux root password reset
In Linux, regular users and Superusers are allowed to access services via password authentication like in any other operating system. In the case, a regular user can't remember his/her password, a Superuser (or a root user) can easily reset the password of a regular user right from the terminal. However, what if the Superuser (or root user) loses or forgets his/her password?
The procedure is quite different for recover the lost password of a superuser (or root user). Nonetheless, this method of recovering a lost password also allows any malicious user with physical access to your Linux host to gain complete ownership.
Note: This method of resetting a root password is similar for most distros. In this article, we are using Kali Linux. Also, we will be using "root password" throughout the tutorial, but it can refer to a superuser's password, too.
This guide will provide you with information on resetting lost or forgotten root (administrator) passwords on Kali Linux.
In this tutorial, you will learn:
1) What is kali Linux
Kali Linux can be considered the number one security operating system of today.

Pen-testing is a methodology or a technique in which people check or test their own systems and their architectures to find vulnerabilities. Kali Linux is a Debian-based system and is widely considered as one of the best options for hackers too. Kali Linux was developed by offensive security as a rewrite of Backtrack. A Linux distribution is generally most focused on security. Kali Linux offers many hacking and penetration tools that are up-to-date and software by default and is widely recognized by different Windows users.
