Hello @drmckay,
Welcome to the Fedora Discussion area and the Fedora Magazine section in particular!
+1 for the proposal, I think it is well worth writing about. This is a current topic that is on some peoples minds as can be seen in the discussion area elsewhere.
YubiKey’s are used currently by a number of Fedora users who I am sure will chime in eventually. From their website
Yubico was founded in Sweden 2007 with the mission to make secure login easy and available for everyone. In 2011, Stina, CEO & Founder, and Jakob, Chief Innovation Officer & Founder, moved to Silicon Valley to make the dream happen. In close collaboration with the leading internet companies and thought leaders we created native support for our security keys in the major online platforms and browsers, enabling a safer internet for billions of people.
