How to Change Root Password in Kali Linux?

After completing the installation of the Kali Linux machine the most highly performed task and asked question is to change the root password of your Kali Linux machine.

Note: This is not exclusive only just with Kali Linux machine, you can perform the steps in any Linux machine with grub, we are using Kali as an example.

The default credentials of logging into the new kali machine are username: “kali”  and password: “kali”. Which opens a session as user “kali” and to access root you need to use this user password following “sudo”.

Changing the root password is easy, but you need to ensure these few things:

  1. You are using an active grub boot loader
  2. Your boot loader is not locked

If everything is okay  then just follow the steps:

Step 1: Boot into your machine to grub menu, do not choose anything or boot into Kali.

Step 2: Now you need to edit the grub entries, so you can spawn a root session. Press “e” key to enter edit mode.

Now you need to find the keyword “linux”, in our case you can see that the last line starts with “linux”, which is kernel selection. In our case “/boot/v,linuz-5.5.0.0-kali2-amd64” represents our active kernel.

Navigate in the line to “ro” (read only) and replace it with “rw” (read and write).

In the same line navigate to “quite splash” and replace it with 

init=/bin/bash

These changes are not saved permanently and grub uses default configurations, once you have made these changes press key “f10” to boot. This will create a terminal session with root privileges

Step 3: Once you are in the terminal session you just need to enter the command:

passwd root

After applying your new password reboot your system.
