The man pages for both group 5 and newgrp 1 do not include examples of how to use group passwords.
email@example.com stated that a short example similar to this would do in the newgrp man page
Create the group
% pw group add foo
Set the group password
% pw group mod foo -h 0
As a non root user switch to the group
% newgrp foo
Also in the group 5 man the See Also section should include a refrence to newgrp 1
How-To-Repeat: See man 1 newgrp and man 5 group

Add an example of creating a group, setting a group password, and switching to the new group.
group(5) has a cross-reference to newgrp(1) in the SEE ALSO section.
