@OpojOJirYAlG I assume you used this to decrypt LUKS? Looks like this works fairly different from the GPG way. Looks like an interesting way by itself too.
Using the GPG way the advantage for me at the moment is that I can decrypt with the Librem Key and with the Yubikey if I need to. So if I don’t have the Librem key for some reason I can boot using HOTP and then decrypt with my Yubikey.
Thanks for pointing the Yubikey LUKS out to me though!
