Question about Yubico Key C NFC

This variant can only be used with FIDO U2F and FIDO2 WebAuthn.

According to the comparison site, the more expensive version can also be used with the Yubico Authenticator App and Open PGP.

I am using the keys to communicate with my financial institution in the US and it works well. I have a McBookPro and needed the key for identification as the bank does not send codes to international mobile phones (!). When I changed to a new laptop, I changed to the NFC Key to accommodate a different interface-connection. Otherwise there is not difference in function. For my purposes works well and I have not experienced any problems.

According to my recent experience, this product is not fully compatible with iOS and can be a bit tricky to use with an iPhone. 5C works fine.
