Google has added NFC functionality to both of the latest versions of its Titan Security Key, enabling Google account holders to use them as a second layer of authentication when signing into their account or compatible third-party apps and services by tapping the key on their mobile device. Find out more about the latest Titan Security Keys NFC news below.

Previously, only the USB-A version of the key offered NFC functionality for authenticating with Android and iOS devices, but Google has now added it to the USB-C version as well.

The security keys work in conjunction with Google’s Advanced Protection Program, enabling users to enrol the key to their computer or mobile device and use it “like a second lock after your password” to provide an added layer of protection against phishing and account hacking.

“Since NFC functionality is now supported by a wide range of Android phones and iPhones, we are discontinuing Bluetooth Titan Security Key and focusing on the easier and more widely available NFC capability,” Google explains in a blog post.

“However, for existing users with our Bluetooth Titan Security Keys, these will continue to work with Bluetooth and will continue to work as an NFC key on most modern mobile devices.”

To purchase a Titan Security Key, visit the Google Store. The USB-A+NFC key, which includes a USB-A to USB-C adapter, is available for $30 and the USB-C+NFC key retails for $35.
