Physical security key compatible with Macbook Air?
Is there such a thing as a physical security key, such as Yubi Key (which does not yet appear to be available for Apple devices), that's browser-independent and works for Macbook Air and other Apple devices?
The available security keys seem to require Chrome or Microsoft devices -- and tend to have USB connectors rather than Apple's elite connectors.
