Not sure if to use SSH keys? Or Yubikey? Or Google Authenticator? On a whole bunch of machines?

Why not have it all?

Using privacyIDEA [1] you can

* manage SSH Pub keys for several servers * manage your Google Authenticator centrally * manage Yubikeys centrally or whichever OTP token.

In addition you can combine it to use the Google Authenticator or any other OTP ++PLUS++ SSH keys [2].
