From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Yubikeys support device bound passkeys already.
But you need to buy at least two of them, which isn't cheap.
And... honestly, you should probably buy 3. Losing your main key only to find out that your backup key broke a month ago and you haven't been testing it is a real risk.
Not every service allow for registering more than one passkey
And what are they odds of simultaneous losing / breakdown of all three keys? I think they are not negligible.
I ended up getting one through arstechnica (they sent one if you subscribed back then), then I got more through some sale or something
