The useful frame is not "is this secure" but "what does an attacker get if this one thing goes wrong, and how quickly would we know".
This piece walks through how we think about it at Paycux, what we have changed our minds about, and where the sharp edges are.
How a phishing email is built
That brings us to how a phishing email is built. Detection beats prevention when prevention is uncertain. If you cannot stop a class of abuse outright, make sure it produces a signal loud enough that someone sees it the same day.

Common phishing tactics
Common phishing tactics is where this gets concrete. Blast radius is the metric that actually matters. A credential that can read one organization's data is an incident; the same credential scoped to every organization is a company-ending event, and the difference is a design decision made months earlier.
Rotate on a schedule, not on an incident. A rotation path that has been exercised is a routine change; one that has never been used is an outage waiting for the worst possible moment.
- Scope credentials to the smallest useful blast radius
- Alert on the abuse you cannot prevent
- Exercise the rotation path before you need it
- Log the decision, not just the outcome

Other signals worth checking, with caveats

Where this leaves us
If there is one thing worth taking away, it is that the expensive decisions are the ones made implicitly. Making them on purpose costs an afternoon.
If you are working through the same problem and want to compare notes, the docs cover the mechanics and the console shows the behaviour on your own data.
