Namespace: microsoft.graph


APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

The usage function allows the caller to see which Conditional Access policies reference a specified authentication strength policy. The policies are returned in two collections, one containing Conditional Access policies that require an MFA claim and the other containing Conditional Access policies that do not require such a claim. Policies in the former category are restricted in what kinds of changes may be made to them to prevent undermining the MFA requirement of those policies.
