Can anyone tell me if It's possible to set more paswords on one dedicated server? So that i can People give a special pasword and when that personen is in the server nobody can come in with that pasword.
You can only set one password, everybody who knows that password has access to the server. There isn't a possibility to have multiple password access to one dedicated server instance. For control of a dedicated server there are more passwords possible in the access file in the installation folder, but this is not what you want with your question. If you want a temporary private session, just change the password for that session. Set the more uniform password back after the very private session.
Thanks Rik. Maybe in the future the possibility to invite People for joying your server would be great
