Generating a random password can be done with the openssl in the base system;

    openssl rand -base64 9

You'd want to pipe the output of this command through tee(1) and save it in a
file. Next you pipe it to a file discriptor leading to a 'pw usermod -h
0'. Something like this:

   openssl rand -base64 9 | tee -a newpasswords | pw usermod UID -h 0

where UID is the user-id or name of the user in question.
