I just changed to the YubiKey 5C NFC this past week. I like it. Just wish I could save Nostr private keys on it. Or better - that it could generate NIP-26 keys.

I ditched Google Authenticator 6-9 months ago when I upgraded my iPhone and all the data for Authenticator got lost. Scared the shit out of me and swore I’d never use authentication app ever again. But since YubiKey stores everything on the key, and I can have a backup in a secure place - I feel completely confident using the YubiKey authenticator.
