Dropbox launched support for two-step verification a couple of months ago. Now it wants to make sure you actually use it. The feature enhances security by requiring more than just a password to log into a Dropbox account.
It's also enabled for "enterprise" users, i.e. those that signed up for Dropbox for Teams.
Now, Dropbox is making it possible for admins to check whether the people on their team have enabled the feature or not and enables them to send out an email to those who haven't.
This should make it possible for admins to more easily enforce better security practices. Making sure everyone enables two-step verification makes it harder for outsiders to access critical files and is a good idea even if you think you have nothing to hide.
