FIDO U2F Security Key Issue
I'm unable to register our FIDO security keys from a browswer on my PC, but I was able to register them via a browser on my phone .
I tried to register FIDO security keys to my Yahoo account via Chrome on my PC running Windows but kept getting an error. I then tried to add the same keys via Chrome on my Pixel phone and I was able to successfully add them to my account. It seems that Yahoo is using FIDO2 protocol for the key registration via Chrome on PCs, but it’s using FIDO U2F to register via Chrome on Pixel phones.
