AWS Cognito vs IAM role in Android APP for security aspects -


an app of mine in android playstore (let's >1.000.000 installs) collect anonymous statistics. want store , work these statistics on amazon emr cluster.

currently use aws cognito creating unauthorized access uploading data s3/firehose. saving money thought of changing procedure use hardcoded iam user, able upload data fh/s3. don't need identification of each user.

what disadvantages should expect in terms of security?

cognito federated identities 100% free. switching iam user won't save money.

per pricing page: "using federated identities feature authenticating users , generating unique identifiers free amazon cognito."
