Does a group created using `groupadd` have a default password?

Question

I created a group using the following command:

sudo groupadd myGroup

Then I tried to run gedit and set its primary group to myGroup:

sg myGroup gedit

But sg is asking me for what I assume is the group password.

Does a group created using groupadd have a default password?

Edit:

When I make myGroup part of my user's groups, then sg no longer asks me for the group password. But I do not want to make myGroup part of my user's groups.

No, by default groupadd doesn’t set group passwords (which means they are disabled, and only users who are members of a group can use the group). To set a password, use the -p option to groupadd (but read its documentation first), or better yet, run gpasswd.
