How to enable sFTP in a Linux VPS?

The SSH File Transfer Protocol (SFTP), also known as the Secure File Transfer Protocol, enables secure file transfer capabilities between networked hosts. Unlike the Secure Copy Protocol (SCP), SFTP additionally provides remote file system management functionality, allowing applications to resume interrupted file transfers, list the contents of remote directories, and delete remote files.

The command-line secure file transfer program (sftp) and graphical SFTP clients, such as Filezilla, WinSCP and Fetch, use SSH2 encryption to authenticate and establish secure channels between networked hosts. Although SFTP clients are functionally similar to FTP clients, they employ different protocols; consequently, you cannot use a standard FTP client to connect to an SFTP server.
 
Note: You can only have only a single sftp account in one cPanel. You can't have multiple sftp in one cPanel.
