How do I access my existing SSH key or generate a new one?
You will need to generate a new public/private key pair for every computer you need to authenticate. For a refresher on how to generate a new key, revisit this lesson if you have a PC and this lesson if you have a Mac .
You don’t ever want to copy a private key onto another machine, so don’t do this through the network or removable media. You can list all the public keys you have by typing in the terminal: $ ls ~/.ssh/*.pub
