I have noticed that after some update, the Pi now requires a password for rebooting or shutting down. I have a Pi 3 and I am accessing my Pi via VNC and doing the shutdown/reboot from the GUI (not the command line), if that makes any difference.

Is there any setting I can update to disable this password requirement for reboot/shutdown?


After tlhIngan's post, I did some more experimenting and it is as if the GUI for shutting down the computer is no longer prefixing shutdown or reboot with sudo. Next, I opened up a terminal and entered reboot (no sudo and I get the same password dialog). I may need to file a bug report for this...

Pi Reboot Password

  • If they've changed something this way it is most likely apparent in /etc/sudoers or a file in /etc/sudoers.d if it exists -- if not it's some dunderheaded functionality added to the GUI interface and you will not be able to modify it.

  • I've had this same problem recently. After reinstalling Raspbian it disappeared for a week or so, but today it started happening again.

  • After doing some testing, I figured out that this only happens when I connect to my Pi remotely using VNC. I also have to enter a password to mount and eject a USB flash drive. I wonder if this is related to something I noticed in the release notes for the latest version of Raspbian (4.4): "Removed sudo from shutdown options"

Raspbian comes configured by default to not require passwords for sudo commands from user pi. If you are using a different user account or if this no-password requirement has been changed by an update, here's how to change it back.

  • I added some new information and clarifications to my original post.
