Daily insecurity output on valid users using key with valid shell and without password.

I find this annoying and sometime I over look this because I always get
the example:

==============
Running security(8):

Checking the /etc/master.passwd file:
Login share is off but still has a valid shell and alternate access files in
home directory are still readable.
Login xxx is off but still has a valid shell and alternate access files in
home directory are still readable.
=========

Is there a better or different way to do this?

I always disable the login password on users with * oppose to password
in the master.passwd file after keys are installed as I DO NOT want to
allow login password when ssh keys are use, but still get the above
warning daily on multiples servers & users.

The Running security(8): is nice as you see possible changes done by sys
admin and you get the feedback, but getting daily warning for the same
things sometime will get overlook because of noise.

Is there a better way to disable login and not get these warning for ssh
key users and keep the valid idea and use of the cronjob as is?
