I suspect it has to do with Fastmail's move from U2F to Webauthn.
Your key MANY not be backward compatible. Or your Browser may not support Webauthn. What browser are you using? |

I hope you are wrong... it is impossible to cut me out from possibility to log in, if it was possible earlier, without any warning!

I did delete and reregister a couple of my YubiKeys and noticed that they now say Webauthn vs U2F on the list of security keys. |

FYI Resolved: I had to register the same key once more and delete previous registration of that key.
