We have already commented on this on more than one occasion – enabling a two-step verification for all services that we use (Gmail, Facebook, etc) is a basic security measure that we should not overlook. It requires a bit more effort than simply entering a password, yes, but the protection it offers you is worth it. The confirmation might be a code that arrives by SMS to your mobile phone, an automatic call in which a robot reads the code, an email that you receive within the associated service, or a notification in the app. The bottom line is that it makes it harder for the attacker to access your account as they won’t have the code available. However, the techniques thought up to circumvent the two-step verification have become more sophisticated. Cybercriminals can create webpages almost identical to the official pages of Google or Facebook, for example, which will demand the verification code sent to your mobile phone. This way, if they manage to fool you, they can access your account without needing to have the device which contains the code. The answer to all this has arrived in the form of a pen drive. Led by Google, FIDO Alliance is developing a technology (U2F Security Key) that makes it imperative that you have the gadget in order to access the account. This gadget is a USB device that can be purchased for under 6 euros through Amazon. Google accounts are also now supported if you access it through the Chrome browser.
