I have a program that I'm writing where I want to secure access to with a username and password. I thought it would be easier if my program simply checked the Windows username and asked the user to re-enter the password in order to access my program. If I can do this, then I don't have to worry about allowing the users to change their passwords in my program (or usernames for that matter)....instead, they would go to control panel for this. Is this a good idea and one that should be trashed immediately? Any tips you have will be greatly appreciated.
