> Both UAC and sudo are just OS level cookie dialog boxes To be fair, that's misconstruing UAC and CredUI/Secure Desktop a little. There probably is merit in switching to an isolated desktop session when seeking consent, or user credentials, despite the fact that UAC/the AuthZ part within a user account has flaws. I think another issue is probably that most user's exposure to UAC is on machine's they're the sole user and administrator of; it's a different ballgame in enterprises where the end user is probably the least privileged principal logged into a particular PC. Windows et al have Sandboxed apps, but which apps and which users should be allowed to do system-level confirmation type changes? iOS and Android are (for the most part) on single user devices, you still need some sort of AuthZ system to decide who and which apps can change what on multi-user systems.
