I’m looking to get started with hardware keys. My use case is (to start with): Running vaultwarden instance and would like to lock/unlock vaultwarden with hardware key and vaultwarden takes care of actual password storage
I’m looking at solokeys just because of open source nature, however I didn’t find much info about protocol support.
For Yubikey 5C NFC I see following
Multi-protocol: YubiKey 5 Series is the most versatile security key supporting multiple authentication protocols including FIDO2/WebAuthn (hardware bound passkey), FIDO U2F, Yubico OTP, OATH-TOTP, OATH-HOTP, Smart card (PIV) and OpenPGP.
I don’t yet use OTP / PIV etc. Is there a tabular form of comparison between 2? Is there any downside in getting solokeys?
Iirc they do not have piv but otherwise are basically identical. Feitian is another company making keys and they do U2F+OTP+CCID normally
Edit: looks like U2F/FIDO2 only, https://github.com/solokeys/solo1/issues/208
But that’s solo1, is it same for solo2 as well?
