This will probably be a short and informative question.
All the time I have heard and seen people talking about how you can customize sudo so you can adjust the 15 min reset, and add a custom query for the password. I myself would like to know how, and do this(At least on debian based systems). I have DuckDuckGo'd it and I couldn't find anything except the "Sudoers File" in /etc/sudoers, which I haven't found a way to adjust or configure anything from there.
Can anyone tell me the file or where I can configure these settings?
