In the remainder of this article, we show you how to find or create your key pairs. Moss helps you manage your public keys on all your servers. Public key authentication is based on key pairs: a private key (usually in a file named id_rsa) that you only know, and a public key (usually in a file named id_rsa.pub) that is uploaded on any server you want to access.
So if you ever need to log into your server, transfer files, or the like, using this kind of authentication, you need to understand how it works (use password auth otherwise). For security reasons, Moss recommends public key authentication in the servers it helps you manage.
The SSH protocol allows you to authenticate on a server using different methods, most commonly via password or public key.
