Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Local authentication
Local authentication in Power Pages allows external users to self-register with an email and password, which is stored in the portal's contact table. This is the standard approach for external self-registration. Option A (Microsoft Entra ID) is incorrect because it is primarily used for internal employee authentication, not for external self-registration. Option B (SAML 2.0) is an enterprise federation protocol designed for single sign-on with external identity providers, not for direct self-registration. Option C (OpenID Connect) is an authentication protocol, not an identity provider, and is typically used for SSO scenarios, not self-registration. Therefore, only local authentication supports built-in self-registration for external users.
