Author here - thanks for the feedback. As another reply points out, I did try to also cover the use of a bastion host along with one form of 2-factor authentication.

I'm considering doing a future post on how to set up U2F for SSH with hardware devices (like a Yubikey) as well. I'm curious if you have anything else you'd like to see on this topic.
