Dropbox announced today that it is rolling out a new security feature to all its users. The new feature will make the end user experience in Cloud storage service much more safe, since Dropbox released a new way to connect with security keys Universal 2nd Factor as a complementary method for two-step verification. 
This means that users of the service will be able to use USB keys as a two-factor connection verification in the Dropbox.
Security keys are a much easier way to log in to dropbox.com. After entering your code you put the key in door of USB when prompted.
The method, although similar to the one using a phone, is much easier to use, since you don't have to worry about running out of battery deviceς σου.
To set this two-way connection method you will need a special USB that is compatible with the FIDO Alliance open standard and is called FIDO Universal 2nd Factor.
Settings are available today in your Dröpbox account, along with similar U2F-enabled services.
