If the password field contains some string that is not a valid result of crypt(3), for instance ! or *, users will not be able to use a unix password to access the group (but group members do not need the password).
The password is used when a user who is not a member of the group wants to gain the permissions of this group (see newgrp(1)).

A password field which starts with an exclamation mark means that the password is locked. The remaining characters on the line represent the password field before the password was locked.
