Also if I want to add a 2nd key via the SSO account its not clear how to do it. It doesn't happen automatically and I can't find any documentation on how to "sync" my Ubuntu Core with SSO to get the 2nd key. The only way to do this is manually via my original machine which doesn't seem right - see also this Q: http://askubuntu.com/questions/865334/cant-login-to-ubuntu-core-16-using-a-second-ssh-key
