MKPASSWD(1)                                                        MKPASSWD(1)



NAME
       mkpasswd - generate new password, optionally apply it to a user

SYNOPSIS
       mkpasswd [ args ] [ user ]

INTRODUCTION
       mkpasswd  generates  passwords  and  can apply them automatically to users.  mkpasswd is based on the code from
       Chapter 23 of the O'Reilly book "Exploring Expect".

USAGE
       With no arguments, mkpasswd returns a new password.

            mkpasswd

       With a user name, mkpasswd assigns a new password to the user.

            mkpasswd don

       The passwords are randomly generated according to the flags below.


FLAGS
       The -l flag defines the length of the password.  The default is 9.  The following example creates a 20  charac-
       ter password.

            mkpasswd -l 20

       The  -d flag defines the minimum number of digits that must be in the password.  The default is 2.  The follow-
       ing example creates a password with at least 3 digits.

            mkpasswd -d 3

       The -c flag defines the minimum number of lowercase alphabetic characters that must be in  the  password.   The
       default is 2.

       The  -C  flag  defines the minimum number of uppercase alphabetic characters that must be in the password.  The
       default is 2.

       The -s flag defines the minimum number of special characters that must be in the password.  The default is 1.

       The -p flag names a program to set the password.  By default,  /etc/yppasswd  is  used  if  present,  otherwise
       /bin/passwd is used.

       The  -2 flag causes characters to be chosen so that they alternate between right and left hands (qwerty-style),
       making it harder for anyone watching passwords being entered.  This can also make it  easier  for  a  password-
       guessing program.

       The -v flag causes the password-setting interaction to be visible.  By default, it is suppressed.


EXAMPLE
       The  following  example creates a 15-character password that contains at least 3 digits and 5 uppercase charac-
       ters.

            mkpasswd -l 15 -d 3 -C 5
