Then click on Set password.
Enter your my.world4you.com password (= the password you used to access the customer area!)
You will then receive the SSH access data. Save these access data separately immediately, as they are only displayed once!
You can establish an SSH connection to your web space with these access data.
Use
in Windows a SSH client, such as PuTTY,
in MacOS the terminal.
