Your company needs to develop an application that needs to have a login module in place. Their key requirement is to ensure that users can also use their current identities with various providers such as Facebook to log into the application. Which of the following can help you accomplish this?

Answer options:

A.Using the AWS Cognito service
B.Using the AWS Config service
C.Using the AWS SQS service
D.Using the AWS WAF service

Answer – A
The AWS Documentation mentions the following.
Amazon Cognito provides authentication, authorization, and user management for your web and mobile apps. Your users can sign in directly with a user name and password, or through a third party such as Facebook, Amazon, or Google.
The two main components of Amazon Cognito are user pools and identity pools. User pools are user directories that provide sign-up and sign-in options for your app users. Identity pools enable you to grant your users access to other AWS services. You can use identity pools and user pools separately or together.
Option B is incorrect since this is a configuration service.
Option C is incorrect since this is a messaging service.
Option D is incorrect since this is a web application firewall service.
