On the other hand, once a security key is added to a Google account's settings, NFC keys can be used right away without going through a 'pairing' procedure, with users being able to immediately verify login operations just by bringing the NFC security key next to a device without any other prompts. This decision might be related to the fact that Bluetooth keys need to be paired with a device-such as a smartphone or a laptop-before they can be used, something that might not be intuitive for non-technical users. Google did not disclose why it was discontinuing its Bluetooth-based security keys but only said that since NFC functionality is now broadly available on modern smartphones, it decided to focus on this technology since it's easier to use compared to Bluetooth keys. However, when USB ports are not present, security keys can provide the tokens via Bluetooth or NFC-based radio connections. The token is usually provided by connecting the security key to the user's device via a USB connection. Once a user enters a correct username and password, they are asked to provide a cryptographic token generated on the security key. Security keys usually serve as a second verification factor in login operations, on top of an account's credentials. Google said the USB-A (+NFC) key, which includes a USB-A to USB-C adapter, will be available for $30, while the USB-C (+NFC) key will be sold for $35.

Only two security key models will be available from tomorrow, namely Titan keys with USB-A and USB-C connectors, both of which also support NFC (Near Field Communication) for mobile connectivity. Google has announced plans today to discontinue its Bluetooth-based Titan security keys and focus on NFC-based versions going forward.Īs part of this decision, starting tomorrow, August 10, the company will stop selling Bluetooth-based Titan keys on its official store.
