I know, right? Not that it would be easy. <i>ssh-copy-id</i> is kind of an idea of how it could work, but that suffers from bootstrapping issues and doesn&#x27;t seem to be supported except in very specific PaaS situations. A useful tool would have to dig into the idiosyncrasies of each service&#x27;s auth policies, at least until it became popular enough that services would try to meet it halfway.
