Caption notes
The talk uses a third-party app reading contacts to separate two questions: what is the app allowed to access, and who signed in? The speaker explains delegated authorization through OAuth 2.0: the app can receive an access token for limited permissions, such as reading contacts. He then uses OpenID Connect to explain identity at sign-in. The ID token carries information about the authenticated user to the app, while the access token is used to access authorized resources.
