---------------------------------------------------
Format of /etc/group:
<Group name>:<Encrypted Password>:<Numerical Group ID>:<Individual
user names that are part of the group:'Group name'>

Format of /etc/passwd:
<userName> : <Encrypted Password> : <Numerical user ID> : <Numerical
Group ID> : <Comment Field> : <Initial Working Directory> : <Initial
shell>
---------------------------------------------------

As I understand, it is necessary to adapt only /etc/group to add a
secondary user group to a user.
For any reason, is it required to change /etc/passwd also?  I assume
NO.
In my understanding, we mention only the Primary group Id in
/etc/passwd.

You understand and assume correctly.
The user have to login again though to get the new groups taken into account
.

Our enemies are innovative and resourceful, and so are we. They never
stop thinking about new ways to harm our country and our people, and
neither do we.

And there can also be a gshadow file that has the same function as
/etc/shadow for /etc/passwd, which might also require tweaking...
