How to Change the Super User Password

On the Linux and UNIX operating systems, the super (root) user is the account that handles the administrative duties. These duties include software installation and management, system monitoring and editing configuration files. The super user's account is protected by a password that should be kept secret and changed regularly. The "su" command allows you to switch to the root user account from a regular account, while the "passwd" command allows you to change a password.

• 2

  Type the command "su -" to switch to the root user. Type the current root password when prompted.

• 3

  Type the command "passwd" to change the password.

• 4

  Type the new root password twice when prompted.
