Is SSH public key need to be the same each time I do push/pull with git repository?

Question

I am just started using Git, so I apologize if it is a newbie question.
I am using two different machines to commit changes to remote Git repository on github.com. Do I need to use the same SSH public key (the one I mentioned for my repository on Github)?

Answer 1

No -- if you go to your GitHub accounts page, you can add as many SSH public keys as you want.
