A few days ago, I've updated my Putty configuration to set the default font-size to 12; no more 10.

Today, by starting Putty, whatever on which server I wish to join, I got the No supported authentication methods available followed by, in my case (server sent: publickey, gssapi-keyex, gssapi-with-mic, keyboard-interactive) fatal error.

I've only understand the origin of the problem by looking at the window caption: Putty tries to connect to a server other than the one I want. Why? And, ah, ok, last time I've modified my settings I was working on that server so, the solution should come from: how can I reset my Putty settings?

Using SSH instead of HTTPS to connect to Github is more secure. Indeed, SSH relies on public-key cryptography. This makes unauthorized access much harder compared to a password, which can be stolen through phishing or brute-force attacks. Also, HTTPS transmits your username and password (encrypted) over the network, which can be intercepted in a Man-in-the-Middle (MITM) attack. SSH doesn't transmit passwords after the initial setup.

Let's see how to add a SSH key and, from now, being able to work with Github like using the git@ protocol with git clone.
