I upgraded from a Yubikey U2F to a Yubikey 4 and I honestly have no idea how to configure it. What the heck?pic.twitter.com/6ZNIQLjC7o
You can add location information to your Tweets, such as your city or precise location, from the web and via third-party applications. You always have the option to delete your Tweet location history. Learn more
Hooray! Yes, either deleting config slot 1 or marking it as dormant will mimic the functionality of the more basic "Security Key." Thanks!
Should do. the U2F functions are done by a separate applet afaik (yubikey is really a javacard with some extra bits for HID under the hood)
I think the Yubikey "NEO" manager (misleading name, it works on yk4 too) can also turn off the keyboard HID interface totally
