On YubiKeys that have multiple interfaces, you may want to disable or enable certain interfaces on your YubiKey to restrict or enable access to certain applets that rely on that connection interface. YubiKeys have all of the modes enabled by default.
You can use the steps below to change which interfaces are enabled on your YubiKey. Please be aware that with YubiKey 5 Series devices, the USB interfaces will automatically be enabled or disabled based on the applications you have enabled.
- Download and install YubiKey Manager.
- Open YubiKey Manager.
- Insert your YubiKey.
- Click Interfaces.
- Check the interfaces you want enabled and uncheck the ones you do not.
- Click Save.
- If prompted, remove and reinsert your YubiKey.
Note: You must leave at least one USB interface enabled.
