First method is using private/public keys between local machine and the remote one. As we know, if we try to connect to a server using basic SSH.
To simplify deploying to a server, you can set up SSH agent forwarding to securely use local SSH keys. SSH agent forwarding can be used to make deploying to a server simple. It allows you to use your local SSH keys instead of leaving keys (without passphrases!) sitting on your server.
How to test if agent forwarding is working on GitHub?
