Public key for authorization?

• We use public key authorization. This is the common way of secure authorization for SSH connection.
• GitHub also can authorize you with public key, if you setup it in your GH account. This is mean that you don't have to type your login and password when you interact with GitHub via git e.g. git clone, git pull, etc.
