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.
