How QR code based FIDO Authentication work

[hetin k]

Hi All,

Come to know that in L3, Mobile as Security Key is  introduced.

Can anyone explain how QR code based FIDO Authentication work?

Thanks in advance!

The QR code is only used to link the authenticator to the client. It is not QR-based authentication.

FIDO Cross-Device Authentication uses the newly defined "hybrid" transport which is defined in the upcoming CTAP 2.2 specification. It uses a combination of BLE (for proof of proximity and metadata exchange) and a network-based tunnel provided by the authenticator.
