SFTP
SFTP, the SSH File Transfer Protocol, is used to secure an FTP transfer by passing through an SSH tunnel. Consequently, users can use a simple graphic interface via the FTP client of their choice.
Connecting with SFTP
From Remote access > SSH allow your SSH user password connection permission.

Then from your FTP client, fill-in the SSH connection information. Let us take the example of the test account and the FileZilla FTP client:
- user:
test
- password
- hostname:
ssh-test.alwaysdata.net
- port:
22

Miscellaneous
As with the SSH protocol, SFTP users are not chrooted
. However, it is possible to limit their actions by choosing the SFTP only shell.
This must not be confused with the FTPS protocol: FTP transfer secured by SSL or TLS protocols.
