If you need to change your 'amazon' password, you click 'generate different codes', yes. That action will be remembered in your browser's local storage. So when you need to use your amazon password again, it will automatically advance and generate the correct password.

But if you come from a different browser, you'll need to click 'generate different codes' again to advance to the correct password.

For services where the password frequently changes, I don't think there's a very practical way to use this. At least not across several different browsers.
