Not too long ago, Dropbox was the victim of a security breach. As a result, it said it would cook up a two-step verification system for the service. Now it's here, and you should go turn it on if you keep anything of value in your Dropbox, or even if you don't.
To turn the feature on, you'll have to have the most up-to-date beta desktop version of the Dropbox client. Once you have that, you can hop over to the Dropbox website to set yourself up in the beta and turn on two-step verification.
In practice, it works pretty much like Google's version of the same tech. When you log on, you'll be prompted to enter a limited-time one-use password you can get either by text or by an app like Google Authenticator. Should you lose your phone, you also get a one-time use backup code, but only one, so think about where you put it.
Two-step verification can be a little bit of a hassle, and this feature was just enabled for testing, so it could be slightly wonky. Still, the extra security is worth it; a little inconvenience here and there is infinitely better than having part of your life completely hacked to pieces. [Dropbox via Betanews]
