A use case (warning I've not thought his out very deeply) Abe has shell access via 'ssh' to Server. He wishes Bob and Carol to have access to the server but for whatever reason they don't have SSH. Abe shells in, does the trick for Bob and Carol. Bob and Carol can use the web-based ssh and are happy campers. Or. Abe controls the server via Puppet [Chef, Ansible]. Something you can do with Puppet is disallow SSH access - one does this to remove the temptation to 'cheat' and hand-config the system. Abe has the ability with Puppet to exec this command to let Bob or Carol (or Abe) into the system 'in case of emergency'.
