Hackers say they've stolen millions of Dropbox passwords, though the company says it wasn't hacked. Either way, now may be a good time to update your password.

To play it safe, you should probably change your Dropbox password and enable two-step authentication if you haven't already done so. The process takes less than five minutes, and is well worth it.

Dropbox is asking users who signed up before mid-2012 to change their passwords if they haven’t done so since then.
