In a pure case of closing the barn doors after the horses have come home (and so many corporate Twitter accounts have been hacked), Twitter has announced today the option to implement two-factor authentication. If users opt-in, any sign-on from a new computer will require a code texted to their phone. 

The feature hasn’t been made universally available yet, so keep checking your settings if you want this added security feature.
