Ahah!  Ok.  I suggest a slight rename: FIDO's got tokens and Fido's got FDO, and the two are quite separate.  EAP-FIDO-TOKEN?

Is the intent that the FDO authentication happen each and every time, or just during ownership transfer?

The intent is to do a FIDO authentication every time (maybe with the exception of TLS session resumption, Text for that is still TODO).

But with CTAP v2 you can trigger silent authentication, so the user does not need to touch their FIDO token every time they need to re-authenticate, the token just needs to be available (which is more complex with hardware tokens like YubiKeys, but very easy with OS-backed FIDO implementations)

Cheers,
