On Windows you can configure "Secure Login" so that you have to press Control + Alt + Delect to show the login screen like so:

Secure Login Windows

Does this feature exist on OS X or is there a third-party application that can achive this?

  • Same reason why you would do this on Windows. Prevent a fake login screen from being shown that grabs your credentials. – ecnepsnai Sep 15 '15 at 19:39
  • I don't think that can happen in Mac, also I only see these on public computers. – user14492 Sep 15 '15 at 19:42
  • It's a setting controlled in group policy and is enabled when you join a Windows computer into a AD domain. – ecnepsnai Sep 15 '15 at 19:43
  • @ecnepsnai, CAD can be enable on a stand-alone PC running Windows and doesn't have to be connected to anything for that matter. – user3439894 Sep 15 '15 at 21:23

Short answer: No. This feature does not exist on Macs.

On a side note, it's also useless in Windows too.

A long time ago in a galaxy far, far away, CTRL+ALT+DEL sent a hardware interrupt to the PC's BIOS (which would immediately reboot the computer in the DOS days).

That interrupt also had the happy side-effect of breaking things like keyloggers and programs designed to steal your password, so when Windows NT arrived on the scene, Microsoft trapped that interrupt to prove that you were a real, live human sitting in front of a keyboard.

That has not been the case for many, many years. I have no idea why we're still dragging this stupid three-finger salute around after all these years (tradition maybe?) It offers no meaningful security these days and I personally disable it with Group Policy on every domain I administer.
