Usage guidelines
Without first-time authentication, a client not configured with the server's host public key does not
access the server. To access the server, a user must configure in advance the server's host public
key locally and specify the public key name for authentication.
With first-time authentication, when an SSH client not configured with the server's host public key
accesses the server for the first time, the user can continue accessing the server, and save the
server's host public key on the client. When accessing the server again, the client uses the saved
server host public key to authenticate the server.
Because the server might update its key pairs periodically, a client must obtain the most recent host
public key of the server for successful authentication of the server.
