Another layer of security for your Dropbox account:
Hi everyone! A few weeks ago, we discussed a number of steps we’re taking to add an extra layer of security for Dropbox users. Today we’d like to announce the launch of two-step verification, a feature that will enhance the security of your Dropbox by requiring two levels of authentication: your password, and a security code that will either be texted to your mobile phone or generated by a mobile authenticator app (available for iOS, Android, Blackberry and Windows Phone 7).
