  1. Connect to your server and open the command line
  2. Type “passwd” and press enter
  3. Enter your new password
  4. Repeat your new password to confirm your password
  5. You changed the password
  1. Log in to your server as the root user

  2. Use the adduser command to add a new user to your system.

    Be sure to replace username with the user that you want to create.

    • "adduser [username]"
    • Set and confirm the new user’s password at the prompt. A strong password is highly recommended!

      Set password prompts:
      Enter new UNIX password:
      Retype new UNIX password:
      passwd: password updated successfully
    • Follow the prompts to set the new user’s information. It is fine to accept the defaults to leave all of this information blank.

      User information prompts:
      Changing the user information for username
      Enter the new value, or press ENTER for the default
          Full Name []:
          Room Number []:
          Work Phone []:
          Home Phone []:
          Other []:
      Is the information correct? [Y/n]
  3. Use the usermod command to add the user to the sudo group.

    • "usermod -aG sudo username"

    By default, on Ubuntu, members of the sudo group have sudo privileges.
