Configure sudo without password on Ubuntu 22.04 step by step instructions

  1. First you might want to consider to disable sudo password only for a selected administrative command(s). To do so you need to edit the /etc/sudoers sudo configuration command using the sudo visudo editor. For example, to allow a single user eg. linuxconfig to execute the systemctl and reboot commands without sudo password add the following line into the /etc/sudoers configuration file: 
    linuxconfig ALL=(ALL) NOPASSWD:/usr/bin/systemctl /usr/sbin/reboot

    At this point executing the systemctl and reboot commands will not require sudo password.

  2. Next, if you wish the linuxconfig user to execute all commands using sudo with no password change the configuration line from Step 1 to: 
    linuxconfig ALL=(ALL) NOPASSWD:ALL
  3. Lastly, in case you need all members of the sudo group to execute any commands using passwordless sudo, change the configuration line from Step 1 to: 
    %sudo   ALL=(ALL:ALL) NOPASSWD:ALL
