AWS Certified Developer Associate DVA-C02 Practice Question
A developer is building a new mobile application on AWS and needs to implement user sign-up and sign-in functionality. The requirements state that users must be able to register and authenticate using their existing social media accounts, such as Google or Facebook, to provide a seamless user experience. Which AWS service should the developer integrate into the application to meet this requirement?
Amazon Cognito is the correct service for this scenario as it enables identity federation, allowing users to sign in through social identity providers like Google and Facebook. This simplifies the sign-up and sign-in process for the mobile application. AWS Security Token Service (STS) is used to grant temporary, limited-privilege credentials and is not a user directory service. AWS Certificate Manager handles SSL/TLS certificates to secure network communications, and AWS Key Management Service (KMS) is for creating and managing encryption keys to protect data.
