Wired is reporting that Twitter has a two-step verification system currently undergoing internal testing that Twitter hopes to roll out to its users "shortly". A two-step verification system would help prevent Twitter hacks from happening, like what happened today with the @AP.
There aren't any details on how the two-step verification system would work exactly but hopefully it comes out soon. It's an embarrassment that Twitter has taken so long in implementing more security layers than just a simple password, especially since so many others (like Google, Apple, Dropbox, etc.) have added their own two-step verification systems.
