Thanks will look into it. Should I order it from thier website or third party vendors are safe enough?
Yea it's one of the best, dunno the latest alternatives. Respected one. I use the "YubiKey 5C NFC", there are other ones to suit your usage... I needed USBC one for all devices. You can find more here

Since you'll do it once in your life for many years, maybe direct might be better. Amazon has them too 🤣 but at least Yubico will get more money, and amazon less this time..... for security purposes. I went directly myself just to be pure just like with hardware wallet etc. Unique and rare enough to purchase directly with peace of mind in my opinion
Got it. Thanks for the info.
