So often I see these kinds of phishing attacks that have hugely negative consequences (see the MGM Resorts post earlier today), and the main problem is that just one relatively junior employee who falls for a targeted phishing attack can bring down the whole system.

Is anyone aware of systems that essentially require multiple logins from different users when accessing sensitive systems like internal admin tools? I'm thinking like the "turn the two keys simultaneously to launch the missile" systems. I'm thinking it would work like the following:

1. If a system detects a user is logging into a particularly sensitive area (e.g. a secrets store), and the user is from a new device, the user first needs to log in using their creds (including any appropriate MFA).

2. In addition, another user like an admin would need to log in simultaneously and approve this access from a new device. Otherwise, the access would be denied.

I've never seen a system like this in production, and I'm curious why it isn't more prevalent when I think it should be the default for accessing highly sensitive apps in a corporate environment.
