SFTP (SSH File Transfer Protocol) is required in order to use private key authentication features.
In order to use private key authentication, first ensure that your FTP server supports SFTP (SSH) public/private key authentication.
Next, use your FTP server software to generate a public/private key pair (if you haven't already). Normally you'll also need to associate the corresponding public key to one or more user account. This this process is server-specific, so consult your server documentation as needed.
