On YubiKeys that have multiple interfaces, you may want to disable or enable certain interfaces to restrict or enable access to certain applications that rely on that connection interface. YubiKeys have all of the modes enabled by default (with the exception of YubiHSM Auth, which is only used to protect access to a YubiHSM 2). Follow the steps below to change which interfaces are enabled on your YubiKey.
