Our favorite is the Bluetooth/NFC/USB-A model, which gives you multiple options for connecting.

Google released its proprietary security key line in the fall of 2018 with options for all kinds of people. A one-year warranty is included on this model, making it ideal for those seeking a reliable key at a low cost. The Thetis Fido U2F has a particularly excellent design, made out of an aluminum alloy with a flip-around system that lets you hide the USB port for better protection in your pocket or case. It does lack email compatibility, however. The highly-affordable Thetis USB-A and Bluetooth key is a reliable model that will work with all FIDO U2F compatible data - this includes Chrome browsers MacOS and Linux services like Dropbox, Salesforce, and Facebook and mobile devices with Bluetooth Low Energy. We also like the simple design, including a small hole you can loop a string or chain through for more comfortable transportation. This feature makes the 5 NFC ideal for those who need to manage hundreds of services with a single key or wish to secure individual browsers and operating systems. The Yubico 5 NFC also supports many authentication protocols beyond the common FIDO (U2F) and FIDO2/WebAuthn, as well as Smart Cards and OTP if you want alternative or more open-source security options. The key works with iOS and Android, so it has more usability than the average USB key, which doesn’t typically work with phones. This feature is particularly handy when using smartphones. The NFC tech means that instead of plugging it in, you can just tap the key against the right devices to activate the authentication. Yubico’s series 5 NFC keys work well with both USB-A and USB-C ports and Near Field Communication.
