Question
A company is launching a mobile app in the AWS Cloud. The company wants the app's users to sign in through social media identity providers (IdPs). Which AWS service will meet this requirement?
Options
- AAWS Lambda
- BAmazon Cognito
- CAWS Secrets Manager
- DAmazon CloudFront
Explanation
Amazon Cognito is the right choice because it is AWS's dedicated identity and access management service for applications, providing built-in support for federation with social identity providers such as Google, Facebook, Apple, and Amazon, allowing users to sign in using their existing social media accounts.
AWS Lambda (A) is a serverless compute service used to run code in response to events - it has no built-in capability to manage user authentication or identity federation.
AWS Secrets Manager (C) is designed to securely store, rotate, and retrieve credentials and secrets (like API keys and passwords), not to handle user sign-in or identity provider integration.
Amazon CloudFront (D) is a content delivery network (CDN) used to distribute content globally with low latency - it plays no role in user authentication or social login.
🧠 Memory Tip: Think of Cognito = "Recognize" - just as you recognize someone's identity, Cognito recognizes who your users are by connecting with social IdPs. If a question mentions user sign-in, authentication, or social login, Cognito is almost always the answer.
