I just got my Yubikey 5 NFC, and would like to use it for
- Linux desktop login
- Linux KeePassXC (which only supports hmac-sha1 challenge-response)
- online accounts
When reading about U2F it seams to be the preferred protocol, but TOPT is often only supported on online accounts.
Right now I got Linux login to work with Yubico OTP.
Is it correct understood that in my correct case, I would need to one more YubiKey?
2 slots seams very limited, when just U2F and TOTP would take up those two slots leaving no room for Yuboco OTP and hmac-sha1 challenge-response.
Are there some corners that could be cut?
