A. When a new player signs up, use an AWS Lambda function to automatically create an IAM access key and a secret access key. Program the Lambda function to store the credentials on the player’s device. Create IAM keys for existing players.
B. Migrate the player credentials from the Aurora database to AWS Secrets Manager. When a new player signs up, create a key-value pair in Secrets Manager for the player’s user ID and password.
C. Configure Amazon Cognito user pools to federate access to the game with third-party identity providers (IdPs), such as social IdPs. Migrate the game’s authentication mechanism to Cognito.
D. Instead of using usernames and passwords for authentication, issue API keys to new and existing players. Create an Amazon API Gateway API to give the game client access to the game’s functionality.
