[I][QUOTE]Over the next couple days we will roll out a major upgrade to Microsoft account, including optional two-step verification to help keep your account more secure.
Microsoft has increasingly focused on delivering connected devices and services that are currently used by more than 700 million people around the world. A Microsoft account is the key that unlocks your experience across these products—from your Windows PC to your Windows Phone, from Xbox to Outlook.com, from SkyDrive and Skype to Office and much more.
Given this critical role for Microsoft account, we remain vigilant in working hard to protect your account, which is why we’re adding an option so you can enable two-step verification to further protect yourself. You should see this option show up in your account in the next few days. You can enable this capability at [url]https://account.live.com/proofs/Manage[/url].[/QUOTE][/I]
[b]What is 2 step verification? [/b]
When you sign into an online service, such as Facebook, Gmail, Hotmail, Battle.net, you can set up an added layer of security to your account. By adding either an alternate email address, code generator (smart phones) or simply a text message to your phone, you're sent a code and must input that code to sign into your service.
It's been around for a while on other service, but I'm glad to see Microsoft finally making the adjustment. This is for their at hotmail and at outlook email addresses along with their other suite of services. Do you use 2 step verification on you online services? Off the top of my head, just thinking of major outlets that have 2 step verification:
Facebook
Google/ at gmail
Battle.net Authenticator
Steam Accounts
Apple/iTunes/iCloud; has application specific passwords
[B]Microsoft - Hotmail/Outlook jumps on board.[/B]
..is Twitter next?

If you can set up two factor authentication on your Windows Live ID, you should. I recommend using the variety that relies on an authenticator application (like the battle.net authenticator) on your smartphone, so you don't have to be concerned with text messaging costs and delays.
