You can now use the SSH key stored on your local machine to connect to your remote server.</li>
<li>To connect to your server with SSH, enter the following command.
Replace <code>PATH_TO_PRIVATE_KEY/PRIVATE_KEY_NAME</code> with the path to your private SSH key.
Replace <code>SERVER_IP_ADDRESS</code> with your server&#x27;s IP address.</li>
