Why does my 'ubuntu' user not need a password when using sudo

Question

In the default ubuntu amazon image, it's not required to use a password to use sudo.

To allow someone to do this with sudo, generally I need to add a line to sudoers such as:

%sudo ALL=(ALL) NOPASSWD: ALL

However, the default configuration file doesn't mention NOPASSWD anywhere. How is this configured?

It is built into the amazon image. Google cloud does the same. — Rinzwind, Oct 18 '20 at 17:40

I would search in /etc/sudoers.d folder.

cd  /etc/sudoers.d
grep NOPASSWD *

It will survive systemupdates, it is discussed in https://askubuntu.com/questions/930768/adding-local-content-in-etc-sudoers-d-instead-of-directly-modifying-sodoers-fi – Oliver Gaida Oct 18 '20 at 18:54
I looked but didn't get anything, just realized it was because the directory is 700 and I assumed it just didn't exists. Thank you! – Evert Oct 18 '20 at 18:56
