How to move your passwords into Apple's Passwords app

If you've just ordered one of Apple's new phones, or you're waiting on an iPhone Duo that Apple's US store says won't ship until late January, here's a job worth doing before it lands. Get every password you own into one place, so the new phone picks them all up the moment you sign in. Apple's free Passwords app does that on iPhone, iPad and Mac, and it'll even import the lot from another password manager or browser.
