/etc/groups

stores the group information.

The first field in this file is reserved for the name of the group.

The second field stores the password for the group (an ! signifies that no password is allowed for this group). You can see that most groups have an x in the password field, and this refers to the /etc/gshadow file where you can store the encrypted passwords.

the third field provides a unique group id.

last field provides the members of this group.
