Review on 🔑 Yubico FIDO Security Key NFC - Enhancing Security with USB and NFC Two-Factor Authentication for USB-A Ports and NFC-Enabled Mobile Devices by Wiktor Popiel ᠌

I took it purely for research reasons - to see what kind of device. At the next purchase, I would focus on the 5th series, but it is twice as expensive. Its pros: An interesting device. As a key carrier for an ES to enter the State Services, only to work on other algorithms for entering foreign sites that support the FIDO standard. You can set a pin code, make it the only factor in two-factor authentication - for example, to enter your Google account, you could only use this device. The NFC module allows you to use this hardware key with a smartphone. Cons below: Unlike the 5th series, there are fewer areas of use - for example, there is no way to write a PGP key to it. But if the task is only to use FIDO authentication, then both the main or backup will do.
