Microsoft is offering enhanced security for email, storage and other services.
People who turn on the new feature will be asked not just for a username and password, but also a second piece of information, such as a temporary code sent as a text message to a phone on file. Users can have their devices remember the second code, so they're not asked for it again and again.
Google Inc. and Facebook Inc. already allow two-step verification as an option.
The security enhancements work with all Microsoft accounts, such as email addresses ending in Hotmail.com, MSN.com and Outlook.com. Those accounts unlock a range of Microsoft Corp. products, including email, Skype, SkyDrive storage, Xbox gaming, Office software subscriptions and Windows 8 machines.
