MYG stands for 'MSN', 'Google' and 'Yahoo'. Microsoft (MSN) provides an official way to provide MSN authentication on your own website but this requires you to become a Microsoft Partner which is expensive! Google on the other hand provides API's to make use of their services on you website, but this requires a verification from the user so that Google allows your scripts to access the user's account, so if you want to authenticate the user and get his name then you need his permission (weird)! Yahoo does not provide any partnership program or API to enable you to authenticate a Yahoo user on your website! In short, you cannot get MGY authentication easily...until now! Using Dinit Software's scripts you can provide MGY authentication on your own website without even tell MSN or Google or Yahoo that you are doing it!
