Simple definition
Microsoft Entra authentication context lets applications request conditional access requirements for sensitive actions.
Purpose and use
An Entra authentication context associates Conditional Access controls with a specific action or resource in a compatible application.
How does it work?
The application or service requests the context; associated policies evaluate requirements such as stronger authentication or device compliance.
Example and verification
Validate the protected action and inspect sign-in logs and policies actually evaluated.
Points to watch
Creating a context alone does not protect a resource that never requests it or lacks suitable associated policies.
In short
The context connects a resource requirement to access controls, with effectiveness depending on integration and active policy.
