It took me round about five hours but ... finally managed to migrate all U2F keys, FIDO2 credentials, TOTP codes and PGP keys from my five Yubikeys to my four new #Token2 smartcards.
Apart from at Microsoft (work account, not my fault), migration worked like a chram everywhere.
Now finally running a PC/SC only smartcard setup for disk encryption, U2F, FIDO2, TOTP and PGP.
Damn, so much security. Oh, and what funny policies of multi factors, FIDO, TOTP and what else you can encounter 😅 ...
@artiom The reason was simply to clean up the mess of five different Yubikeys used for various different things. And about PC/SC in initramfs, you just need to include some binaries and a systemd unit file : https://github.com/LudovicRousseau/PCSC/issues/266
