This is a message sent by using Ms Word 2007 directly. Though this way is quite fast and simple, I’m not sure about the security. How does it send my login info to the WordPress.Com? Is it in an encryption file? And how does WordPress read it? If they can understand each other, do you think Microsoft made a security agreement with WordPress just for this simple thing? I’m not sure. Someone can steal your login info, it’s not secure!
