Instagram is Rolling Out Two-Factor Authentication to Protect Your Account
Earlier this month, Instagram finally added support for switching between multiple accounts in the same app. Now the photo sharing service is adding another oft-requested feature: 2-factor authentication.
That's the security feature that texts a security code to your phone when you're logging into your account to verify that it's actually you doing the login. It makes the login process slightly more cumbersome, but what you get is a lot more protection from people trying to hack in.
