Have you ever wanted to know more about SSH authentication than you have ever wanted? Then this course is for you! We will learn all the wonderful secrets of secure shells together without waking the admins (I don't know where I was going with this analogy, but it made a good title).
There is the humble password authentication method, public/private keys, hardware security keys, smart cards, agents, certificates, donuts, certificate authorities, TOTP, multiple authentication methods, FIDO2, sudo with certificates, and more (probably, maybe).
Often forgotten, and in my opinion one of the bigger challenges, is authorization. Sure you have a users public key, but how do you manage exactly which machines they can access and which they cant?
If you are an administrator, you might learn practical ways to improve your SSH setup for your users.
