>Description:
	The man pages for both group 5 and newgrp 1 do not include examples of how to use group passwords.
>How-To-Repeat:
	See man 1 newgrp and man 5 group
>Fix:

eadler at freebsd.org 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
