Mac OS has a useful utility for generating secure passwords – Password Assistant. While it’s certainly useful, it’s only accessible from within preference panes that require you to enter a password.
I spent some time with Activity Monitor to see if I could determine if Password Assistant was a separate program being called. No joy there, so I turned to my old friend Google.
That’s how I found a utility from codepoetry that calls Password Assistant directly. It’s small, it works and best of all it’s free.
