<p>When Microsoft re-launched Hotmail as Outlook.com last year, it was rebirth for the service. Although it received generally positive reviews, Outlook.com still lacked the two-factor authentication that makes Gmail accounts more secure. Now it looks like that omission is being corrected.</p><p>Two-factor authentication for Outlook.com accounts is coming very soon, LiveSide reports. Although the site doesn't cite specific sources, it does provide screenshots of the coming feature.</p><p>Similar to Gmail, two-factor authentication for Outlook.com will require a user to input a code, sent to a designated phone, after logging in with the account password. Instead of sending it over SMS text messaging, however, the system will be tied to an Authenticator app that generates the code. After downloading the app, the user must pair it with Outlook.com via an onscreen QR code.</p><p>That app is actually already in the Windows Phone 8 store, although it's not clear if it will come to other app stores to accommodate Outlook.com users who don't have Windows Phones. The system may also have an SMS or voice option for receiving the codes (as with Gmail), but there's no indication of that yet.</p><p><a href="http://mashable.com/2013/04/09/outlook-security-2/">Keep reading...</a></p>
