1) Why Group password is hardly used in Unix?<br />
2) In /etc/group all my groups do not have password i.e <br />
&lt;groupname&gt;: :&lt;users&gt; -&gt; the password's field is blank, in this case I believe that the password is not set, but why if users would like to change group i.e newgrp &lt;group&gt; they asked for a password? I checked on /etc/gshadow the following group does not have encrypted password in the file.<br />
3) Suppose that I add a new group by runnning command like<br />

Group Password in Unix

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
