How to make SSH connection between servers using public-key authentication?

Im using unreal engine 4. Is it possible to make a third person mmo with it? with different servers and multiplayer?

• Im making a game (Not putting details for private reasons) I was wondering if while using Unreal Engine 4, you can make a multiplayer game that saves your data and can have different multiplayer servers within the game. So I can play multiplayer and change a buncha stats, and it saves so that when I log in to the game again, or even another server, its still there? Thanks. First time making a multiplayer game, but have made plenty singleplayer ones.

• Answer:

  I'm not an expert with UE4, but what I'd imagine you do is have it so when the person logs off, a file with their stats is sent to a server that would run in a different language and store the data. then if the person logs in, the copy of their stats is sent to their computer. This isn't as secure as other ways. Your best option is using UE4 for the environment, and have all interactions be server based. it will save you plenty of headaches.
