lbschenkel I know it's off topic but I was looking at the code display as an backup option and found that they also have the "MitID Chip". Looking into it's spec, I found that it use the FIDO U2F standard which made me wonder if I could register any FIDO U2F complaint hardware tokens with MitID, like the Yubikey 5 NFC?
Do you know if that is possible?
