Re: I Don't Get It...
how do they know it's you, and not just the person who's stolen your device?
Easy, you obviously secure the private key with a password you enter each time Microsoft sends you a nonce.
They've replaced passwords (plural) with a password. How novel.
Now hackers only have to figure out one secret instead of many to control your whole life. Or, rather, the few sites that care to use Microsoft's new feature.
