I have access to a number of Amazon Linux virtual boxes, that don't like password authentication in general (preferring certificate authentication . . . which authenticates the BOX that is ssh-ing in, but not the WARM BODY between the chair and the keyboard).


On the topic of SSH certificates, they seem fine at first, but when you delve deeper they are a serious security risk because they are are issued by individual users and are effectively unmanaged and unmaintained. In large organisations they are a nightmare to control.

The current best practice is to use a third party authenticator where access control is centrally managed. Even so, automatic authentication means you have no control over the warm body or hacking script that is using it.
