I have a Digital Bitbox bitcoin wallet, which is a killer U2F as well. It can be used as an RSA key as well pretty sure. For my high security servers I use encryption keys from my keepkey wallet.
I also have a fidesmo card which is an NFC secure card for my cell phone to protect my Google Authenticator and password manager on mobile when I need to use it.
I do... u2f for 2FA, and a password vault protected by hardware, and the hardware to sign into ssh using an RSA key.
2FA does secure a bit. I use it for almost every required application now.
I haven't checked the hardware key, except VPN token.
2FA is totally not good, since it's very easy to spoof. U2F is far superior, though not perfect. Security is always layers.
so, you use the vault for almost everything? which one do you use for hardware key?

I think Trezor is working on this.
