Command

public bool IsPreview { get; set; }

Property Value

bool

Remarks

The authenticatorCredentialManagement command was introduced in FIDO2.1. Hence, YubiKeys that do not support 2.1 will not have this feature. However, there was a version "2_1_PRE" which contained the "CredentialMgmtPreview" command. Each "credMgmt" command has a corresponding operation in this preview command.

If the YubiKey does not support "credMgmt" but does support "CredentialMgmtPreview", then set this boolean to true. Otherwise, do nothing, it will be false by default.

When building the APDU, this class will use the appropriate command byte, based on this property.

Note that a YubiKey that supports only "CredentialMgmtPreview" and "FIDO_2_1_PRE" will not support AuthTokens with permissions. In this case, the input pinUvAuthToken will need to be a PinToken.
