Add that ssh-agent starts at the beginning of the X session or login session, and all other windows or programs start and join the ssh-agent program as a client program. By using environment variables, you can locate the agent and use the agent to automatically authenticate when logging on to other machines that use ssh.

In fact, ssh-agent is a key manager. After running ssh-agent, you can use ssh-add to give the private key to ssh-agent for safekeeping. When other programs need authentication, you can send the verification application to ssh-agent to complete the whole authentication process.
