The company’s buying advice is as follows: Meanwhile, the new USB-C + NFC offering comes in at $35. It’s unclear whether Google will keep selling the USB-C only model made by Yubico. That still costs $30 and includes a USB-A to USB-C adapter. This new model joins the existing USB-A + NFC version - again FeiTian - that is unchanged from before. Since NFC functionality is now supported by a wide range of Android phones and iPhones, we are discontinuing the Bluetooth Titan Security Key and focusing on the easier and more widely available NFC capability Previous lineup Support and warranty for that older model will continue. As such, Google will stop selling the old Bluetooth fob - also made by FeiTian - that featured a micro-USB port for charging and connection. This is part of an explicit shift to NFC over Bluetooth given wide mobile adoption. For example, this new model is just the FeiTian ePass K40 with the aforementioned custom firmware loaded. However, all hardware is based on existing designs from third parties.

These 2FA devices feature Google-engineered firmware on the secure element chip to verify the key’s integrity. Inside, there is Near Field Communication (NFC) for 2-Step Verification on phones by tapping. The body features an indicator light and button to confirm sign-in attempts. This latest Titan Security Key is oblong in shape with a USB-C connector at the bottom, while the top has a keychain loop. Google today announced a new Titan Security Key with USB-C and NFC as part of a refresh to its 2FA hardware lineup.
