You connect to SFTP with SSH as follows
- hostaddress: IP or yourdomain.com (replace 'yourdomain.com' with your actual domain name)
- Type: SFTP over SSH
- Port: 7445
- username: your 'account" username (you can only login in sftp with your main account name!)
- password
- rest: autodetect
Note: never store a password in your FTP-client (example Filezilla) since the passwords are stored in plain text!
