Kali Linux, an essential operating system for penetration testers and security professionals, is often used due to its extensive range of tools and security-focused features. However, sometimes users may encounter a forgotten password issue, which can be frustrating. This article will walk you through the process of resetting a forgotten Kali Linux password.
Overview of the Process
This guide will provide a step-by-step methodology for resetting a forgotten password in Kali Linux, including the use of the GNU GRUB bootloader. For those new to the process, the following steps will ensure you can regain access to your Kali Linux installation.
Steps to Reset Kali Linux Password
1. Boot into Kali Linux from Live CD/DVD/USB Stick
If you shipped with a Kali Linux installation media, you can start by booting directly from the Live CD/DVD/USB stick. Alternatively, you can boot your PC from the medium and access the live environment.
Option 1: Boot from the Kali Live Media
1. Insert the Kali Live CD/DVD/USB stick into your PC.
2. Restart your PC and look for the boot device options. Typically, you can hold down a specific key (such as F2, F12, or ESC) to enter the BIOS/UEFI settings and select the USB drive or CD/DVD drive as the boot device.
Option 2: Boot from a Live USB with Lin or Hirens
If you have access to another live media (such as Lin or Hirens), you can use that as well. Both tools offer a comprehensive set of tools for booting your system and performing various tasks, including resetting passwords.
2. Enter the GNU GRUB Menu
After booting from the Kali Live media, you will see the GNU GRUB menu. This menu allows you to select different operating systems or kernels.
3. Select Advanced Options for Kali GNU/Linux
Use the arrow keys to navigate to the Advanced options for Kali GNU/Linux and select it by pressing Enter.
4. Enter Recovery Mode
Once you have selected the advanced options, you will see several choices. Use the arrow keys to navigate to the Recovery mode and select it by pressing E.
5. Modify the Boot Parameters
After selecting the recovery mode, you will be taken to a command line interface. Here, you need to modify the boot parameters to enter a writable mode and gain access to the root shell.
1. Locate the line that starts with linux or linux16, and then append init/bin/bash rw at the end of the line.
2. Press F10 or Ctrl X to reboot the system in recovery mode.
6. Reset the Root Password
Once the system has successfully rebooted, you will be dropped into a root shell. Here, you can proceed to reset the root password.
1. Type passwd root and press Enter.
2. Enter a new password for the root user and confirm it by typing the new password again.
3. You will receive a message indicating that the password has been updated successfully.
7. Reboot the System
After successfully resetting the root password, you can reboot the system.
1. Type reboot and press Enter.
2. When the system reboots, log in with the newly changed root password.
Conclusion
Resetting a forgotten Kali Linux password can be a crucial step in maintaining access to sensitive systems. By following the steps outlined in this guide, you can regain access to your Kali Linux installation without the need for more complex or risky methods. Remember to keep your systems secure by regularly updating and maintaining strong passwords.
