I'm very intersted in the NitroKey 3C NFC model and sad to hear it is delayed. I am looking forward for a TOTP compatible security key that doesn't stop at 15 or 32 or even 50 OTP entries (none exists afaik) and would have a companion authenticator app. Questions: - is there a consensus on the smarphone authenticator app development for OATH-TOTP functionality? - is there an approximate number of OTP entries that can be stored? 50 or 500 or 5000 maybe? - what is the life expectancy of the new model? - is there an ETA for NitroKey 3C NFC?
