CredProtect is required by the security requirements to the FIDO authenticators.

See section 3.4 Privacy, requirement 4.6:

The Authenticator shall implement the CredProtect extension.

Hi @iirachek Thank for your reply.

As my test result, It'll be failed if "credProtect" extension set to userVerificationOptionalWithCredentialIDList(0x02) or userVerificationRequired(0x03). Ext_CredProtected

How do I implement "credProtect" extension in CTAP2.0 authenticator?
