An SSH key file saves the otherwise annoying and error‑prone typing of the hopefully secure and sufficiently long password. Additionally, you may prepare your local desktop to use a short name instead of having to type in a complete FQN hostname.

a.  On your desktop (Linux or macOS), create an SSH keyfile if not already available. It should not be secured by password to enable automatic processing.

[source,]
----
[…]# mkdir ~/.ssh 
[…]# cd ~/.ssh 
[…]# ssh-keygen -b 4096 -C "<YOUR_ACCOUNT>@example.com" -f id_<outputkeyfile>
----
b. Transfer the key file to your server.
+
[source,]
----
[…]$ ssh-copy-id -i $outputkeyfile.pub <YOUR_ACCOUNT>@host.example.com
----

c. Create a config file on your desktop with a convenient host name for your server.
+
[source,]
----
[…]$ vi ~/.ssh/config
Host <MYHOST>
        Hostname host.example.com
        User <YOUR_ACCOUNT>
        ProxyCommand none
        ForwardAgent no
        ForwardX11 no
        Port 22
        KeepAlive yes
        IdentityFile ~/.ssh/$outputkeyfile
----

d. Test the configuration
+
[source,]
----
[…]$ ssh <MYHOST>
