@Pullo : yes I started using SFTP or SSH/FTP (with FireFTP which is really simple and cool) with all my websites now. It's kinda weird to see that this is somewhat exceptional, FTP being the norm. I also followed your advice about keeping credentials in Keepass which I didn't know. This solved my security problem hopefully (I suffered a terrible FTP credentials hacking) and another problem as well : how to keep client information in an organized way. So thanks a lot!
