Answer / safi
THE PERMISSIONS OF /etc/passwd are 644 whereas for
/etc/shadow are 400 .
In /etc/passwd if in a place of password holder a password
is specified (whether encrypted or non-encrypted), it would
be easy to trace the password with hacking tools as EVERYONE
can view this file.
In /etc/shadow file Only owner of the user can view the
shadow file where we find the password in encrypted format.
Thus more safe and secure from end users.
