This is a comparison between YubiKey 5C NFC, currently available for $55 https://smile.amazon.com/gp/product/B08DHL1YDL/ and Feitian ePass K40, currently available for $26 https :// smile.amazon.com/gp/product/B089ZYVCV6/Yybikey has better software, thinner and 1g lighter hardware, and support for much more advanced security key functions like SmartCard PIV etc. On the other hand, Feitian ePass has banging software ( Only Windows, see screenshot), poor documentation and functionality of the Yubikey. However, Feitian only costs half! If you want FIDO and FIDO U2F to protect your regular online accounts like Google, LastPass, 1Password, Facebook, Dropbox, etc. then Feitian is for you. Since Google uses Feitian and Yubikey as providers for its own Titan security keys, there is a reasonable assumption that these two companies have broken Google's strict security barrier.
