This is what was done in the EROS [1] (extremely reliable operating system) UIs - it was not possible for user window to be rendered completely undistinguishable from system windows like, you knew it, a password prompt.

EROS used capabilities to enforce such rules. If you lack a capability to be a system window, you can't pretend to be one.
- amluto 5y agoThis is also what a secure attention key is for. Sadly the well known implementation (Windows NT) made it sufficiently obnoxious that it went away. I can imagine keyboards having a special “password” key and trying to train people that all passwords start with the password key. I don’t know if this would work, but it can’t be worse than Ctrl-alt-delete.
