Question

"FIDO2 Key Attestation Object fmt value None"? Tested with different mobile phones, the result is "none".

The fmt value can be generated in other ways, but the fmt value on the mobile phone is "none".

Please help me...I don't know why.

Any small tips would be greatly appreciated.

Answer 1

Most synchronized keys today are not authenticated, which is why the format is "none".
