Now that all your personal documents and the killer screenplay are stored in the cloud, you probably want to hide them behind a little more than your cat’s name followed by the year you were born.
Two-step verification is the best way to do this. After this is enabled, every time you sign into Dropbox on a new device, you’ll be sent a code to your phone, and you’ll need to enter this as well as your password. Remember that if you lose one of your devices which is already connected to Dropbox, this won’t help, so if that happens you should change your Dropbox password as quickly as possible.
To enable two-step verification, click on your name in the top-right hand corner of dropbox.com, and click Settings.
Then click the Security tab, and click change next two Two-step verification.
This will take you through the process of entering your phone number and linking your account. This makes breaking into your account pretty much impossible.
