In Linux, the root user account is the account that has access to all Terminal commands and files in the system. The root user can modify their Linux system in any way they choose. In most Linux distributions, including the most recent versions of Kali Linux, the root user account is disabled. This is to prevent users from damaging their system. However, you can unlock the root user account pretty easily in Kali Linux using the Terminal. Warning: Use caution when logged in as a root user. Mistakes can cause permanent damage to your system. You should only log in as a root user if you know what you are doing. [1]

  1. Go ahead and use your normal username and password to log in to Kali Linux. Once you set a password for the root account, you can log in using the root account.
  2. On most Linux distributions, you can open the Terminal by clicking the Terminal icon in the Apps menu. It has an icon that resembles a black screen with a white cursor. You can also use the keyboard shortcut to open the Terminal, which is Ctrl + Alt + T .

    Expert Answer
    To reset the root password in Kali Linux, you would typically use the command line "passwd root" before rebooting. After executing the command, you'll be prompted to enter and confirm the new password twice, but note that the terminal won't display the password as you type it for security reasons. Given that Kali Linux is designed for security forensics and auditing, the method for resetting the root password may be different or slightly more involved than other operating systems. Always refer to the official documentation or user guides for accurate and secure procedures.
