Comment (by kdambekalns):

 No, I am not using the YubiKey as a 2FA token. I use it as a hardware
 token, it stores my RSA keys. My SSH is set up to talk to `gpg-agent`,
 which is running as `gpg-agent --daemon --enable-ssh-support`. The result
 is, that by now most tools that can use my native SSH setup work fine,
 with the help of `IdentityAgent ~/.gnupg/S.gpg-agent.ssh` in my

 With "SSH Private Key" set to "None" for the connection, it asks me for a
 password… But when trying to enable the use of a private key, Cyberduck
 forces me to select a private key file–I don't have a file, though, the
 private key is hidden in my YubiKey.
