With identity theft and cybersecurity issues in the news seemingly on a daily basis, better tools to protect our data – and our privacy – are always welcome. For some time, FPF has endorsed the use of two-factor authentication as an “extra” step consumers can take to protect their accounts across a variety of online services. While everyone at FPF uses two-factor authentication for everything from our email accounts to our social media networks, two-factor authentication can be cumbersome and inconvenient. Every time one logs into a different account on a different machine, a code has to be retrieved from a mobile phone. Lose the phone, and you have to hope you have a set of paper-based fallback authentication codes.
Enter the physical security key. Yubico’s new “YubiKey” physical security key, for example, supports both USB and NFC communications and makes two-factor authentication as simple (and as fun) as tapping the device itself. The device is supported by the FIDO Alliance, a non-profit group dedicated to creating strong, interoperable authentication standards. The FIDO protocols that YubiKey follows use standard public key cryptography, and build in privacy by design. This means that the security key cannot track you across services as you log-in, and that local authentication information never leaves the device.
Today Google announced its support for the key, making its use with use with the Chrome browser and Google Accounts enrolled in two-factor authentication much easier.
Google has been interested in physical security keys for a while. The company has been using them internally for years, and last year used its experiences to publish an in-depth look at “Authentication at Scale.” In it, Google explains that investing in password alternatives like public-key-based technologies will help users more easily protect sensitive accounts – like their primary email account or a company’s spokesperson account – from common security threats.
After registering the device with your Google Account, the YubiKey can be easily used to sign into Google services by simply installing the key into a USB port and tapping it when prompted. No more reaching for your cell phone every time you encounter a new computer or clear your cookies. Instead, just plug in and tap! When you’re done, just stick the YubiKey on your keychain and go – it’s waterproof, battery-free and nearly indestructible.
In addition to being potentially easier to use, there are also significant security benefits to using a physical key like YubiKey. Physical security keys can’t be phished and can’t be fooled by fake look-alike websites. They also reduce the threat of man-in-the-middle attacks. And because YubiKey is touch-based, malware can’t silently activate it when you’re looking away. The key can also help users keep an eye out for suspicious activity. For example, when you onto a computer for the first time, you’ll be prompted to tap. If your account suddenly receives a log-in request from a new location, it will also trigger a tap request. If your YubiKey doesn’t authenticate the request, then your account stays locked and Google can flag the failed log-in attempt. Although this may be a small step for security, it is a huge leap for usability.
The benefits from an enterprise standpoint are obvious, but physical keys also point toward a more secure future for consumers, as well. Online, passwords are roughly analogous to the keys we all use to lock our front doors, but the proliferation of online services and the need for ever-stronger and more varied passwords have overwhelmed consumers. Two-factor authentication has helped to make our cell phones our de facto “keys” to the Internet, but permanent security keys may offer even better online security – and convenience. With Google’s support, FPF looks forward to seeing how devices like the YubiKey develop in the future.
