Isn’t it enough to just enter your password once to login, then receive a warning whenever you’re about to do something potentially dangerous?
If it’s such a big security risk, how come the most popular and widely used operating systems in the world and their users seem to be unaffected by it?
I guarantee, most new users coming to Linux from Windows/macOS are going to laugh and look at you funny if you try to justify entering your password again and again and again.
Yeah, and NT was pretty much just a corporate and government thing throughout the 90s. It wasn’t until XP that home users got it on the desktop, and even then, the first user created automatically had all admin rights, because people were still used to the Win9x/DOS way of doing things. Separation of different accounts with different privilege levels wasn’t a widespread practice up until maybe Windows Vista.
