SFTP
Updated: 11/13/2018 by Computer Hope
Short for secure file transfer protocol or SSH file transfer protocol, SFTP is a version of FTP (file transfer protocol) that encrypts data transfers, helping keep your passwords secure and your session private. Because SFTP is a different protocol than FTP, its connection requires that all participating computers that support it. Essentially, using SFTP to connect to an FTP server will not work.
