On initial installs when this is setup, your userID is not added to the
sudoers file itself.  The *wheel* group is what is allowed/setup in
sudoers, and your userid is added to the *wheel* group in the /etc/group
file, such as below..

wheel:x:10:your-username-here

If you wanted to do passwordless, then comment out the line below..

## Allows people in group wheel to run all commands
%wheel        ALL=(ALL)       ALL

And uncomment the line below here..

## Same thing without a password
# %wheel  ALL=(ALL)       NOPASSWD: ALL

In other words, it doesn't add the username/ID itself to the sudoers
file, it goes through the *wheel* group and you add/drop users from
there on need to use basis.
