I got my first computer when I was 14, these ladies were using type writers.  They don't copy and paste.  They will literally try to read it and type the password.  Most of them are on mobile or tablets too.

Also, if they are savvy enough to copy and paste these passwords are a pain in the butt.  You can't double click on them.

I just pulled these out of mandrill and you can see the difference right away.

and as far as "security" goes.  These examples are actual passwords that were just assigned by my site today, but they are completely useless to anyone on here because you don't know who's email is being used.  I've set the lock out to 12 attempts. Good luck! :D
