Which TWO of the following are required to set up a Power Pages site that allows external users to sign in using their social media accounts?
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
✓
Set up the social identity provider in the Power Pages admin center.
Options B and D are correct. To enable social login for a Power Pages site, you must set up the social identity provider (e.g., Facebook, Google, LinkedIn) in the Power Pages admin center (option B) and obtain a client ID and client secret from the social media platform (option D). Option A is incorrect because deploying a model-driven app is not required for authentication; it is used for managing data, not for social sign-in setup. Option C is incorrect because Microsoft Entra ID is typically used for organizational (work/school) accounts, not for social media accounts. Option E is incorrect because local contact records are created automatically after authentication, not pre-created by the administrator.
