Federated Identities for Amazon Entities

There are a couple of different entity types in RDM for AWS sessions; Amazon S3 Explorer, AWS Dashboard, and Amazon EC2 (Synchronizer).

Right now, it requires an Access Key and associated Secret Key in order to leverage.

This requires setting up a User in AWS' IAM and creating an associated pair, however, for environments that rely on federation with alternative identity providers, such as Okta, it is mostly Federated Identities that are assigned an IAM Role and are granted a temporary Access Key at the time of federation,

It would be good if we could somehow have something similar with the existing AWS entity types that would allow us to use these things by providing a login for a federated identity (perhaps it opens a browser so that it can handle authentication+MFA and then grabs the authorization token afterwards?) and then uses the temporary access key for the RDM entity function (like the EC2 synchronizer).
