Although it’s being touted as the first Lightning-compatible security key, the YubiKey 5Ci – which was first shown off at CES in January – also offers a USB-C connection that’s compatible with Android, Mac and Windows devices.
However, despite the addition of USB-C, the YubiKey won’t support Apple’s newest iPad Pros, the company admitted to The Verge.
Nor will the dongle work with any service that supports the FIDO authentication protocol; apps and services will have to add support for the Lightning connector on the 5Ci into their apps.
