Yep, thats the same guide I used a few years ago as well!

I use it daily for Github/ssh in general - and the 2 slots are used for part of passwords for a couple of other things.

I have a couple that are used daily, one in a safety deposit box (which is the "master" key), and a stack of new ones on my desk in case anything breaks. (I used that Cloudflare offer to get a hefty discount on them).

I also have a paperkey copy that lives elsewhere.
