FTP Backup Without Password

Hi,

My hosting provider provide me a backup space for my server. I actually use it with FTP and credentials (login/password) but they also provide an auth by IP so I can connect to it without providing a password (auth is based on IP and Mac address) but I’m not able to put an empty password in the form.

Could you help me to use this type of auth ?

There is a documentation from my provider to explain how it works (Security section) : https://documentation.online.net/en/dedicated-server/tutorials/backup/dedibackup#access_to_the_backup_space

Thanks !
