I meant not generate in Filezilla but that some other Filezilla can download the file without me having to pass passwords.
Exactly. This would be great.
@Alexey Look, just one sample use case: Think of a media professional who shares a movie for a festival. For him it would be an additional security step, to limit the number of downloads to prevent unwanted spreading of the files in question. So he would set the limit maybe to 3 and can rest assured that it cannot be downloaded more often than that.
