The answer is Microsoft Entra ID and local authentication. These two are valid authentication providers for Power Pages because the platform is designed to support both enterprise-grade identity management through Entra ID and simple self-service access via email and password registration. On the Microsoft Power Platform Fundamentals PL-900 exam, this question tests your understanding of which identity options are natively supported in Power Pages versus those that require additional configuration or are not available. A common trap is assuming Windows authentication or standalone Microsoft Accounts work directly, but Power Pages relies on Entra ID for organizational users and local authentication for external or anonymous sign-ups. Remember the memory tip: “Entra for enterprise, local for login”—if it’s not one of those two, it likely needs a bridge like Azure AD B2C.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
