You can use normal ftp or sftp to manage your files. We recommend using sftp (ftp over ssh) over normal ftp being more secure.

How to use SFTP

Your account has an unix user which you can use to access the SFTP (the same logins you use to access ssh)

Details should be as below

Hostname: Server hostname (Use server hostname as ssl service is installed for the hostname. Using domain name will work but will show ssl errors)
SFTP port: 22
User: Unix user
Password: Same password used to access your control panel account

Screenshot below shows a sample settings used in filezilla ftp client for sftp connection

If you need to directly enter the details in the filezilla, use sftp://hostname as the url

How to add normal ftp accounts

Login to control panel, expand Hosting Features menu and then click FTP Accounts

In case you have secondary domains, select the desired domain from the top right (see screenshot below). Click 'Change Domain' option and then select domain name from dropdown

Once the new ftp account is added, simply use details below to connect

Hostname: Server hostname (Use server hostname as ssl service is installed for the hostname. Using domain name will work but will show ssl errors)
FTP port: Leave blank
User: The new user created
Password: Password entered while the ftp account is created.
