Dropbox Testing Two-Factor Verification
Dropbox recently stated that it was working on implementing two-factor authentication for the cloud storage service. The company has now enabled the feature in an "experimental build" and plans to release it to the public soon. Forum users can test it out before an official release by downloading version 1.5.12 and enabling the two-factor authentication option. Dropbox will give users the "option of receiving a text message with a six-number code, or a private list of codes that can be used offline."
