I've followed the instructions on http://support.suso.com/supki/SSH_Tutorial_for_Linux I've created a key and public key, uploaded the key to the remote server and then exited from the remote server. Then, I ssh'd to the remote server and I was able to access it without typing in my password. After this, I closed my terminal session. The next day, when I ssh'd to the remote server, I had to enter my password again. Why is that? Is it because I exited out of terminal? If so, how do I get it to prompt me for my passphrase when I start the terminal? Thanks.
