If you’re so concerned about the security of your Dropbox account that even two-factor authentication through your phone seems too risky, you can rest easy. The cloud storage outfit has added support for USB keys as part of the two-factor sign-in process. Rather than punch in a code, you just plug in a stick to prove that it’s really usb protect you. You’ll need a key that meets FIDO’s Universal 2nd Factor standard, but this key will also work with Google and any other U2F-capable service. Frankly, this is a long-due upgrade – if you regularly access Dropbox from PCs, you won’t have to worry quite so much that someone will get your login details and swipe your files.
At this time, Chrome is the only browser supported. However, Mozilla is currently building support for U2F and Microsoft is working within the FIDO Alliance to eventually bring support to Windows 10. Upgrades to future versions usb protect of the software will be free for minor versions only. For versions after that, upgrades will require additional payment, which will be discounted. It will be discounted only if you’ve purchased the last major version.
For example, a range of vendors now offer software that provides centrally administered and policy-driven control over access to removable storage media and encryption of the data they lock usb contain. I also like that the security exists totally in the device. That is, the security of this external 2.5 inch hard drive does not depend on any software running in any computer.
