Available today; AWS Okta Keyman. This package is a fork of previous work by Nextdoor, Inc. that adds Duo Auth support and has other features already on the roadmap.
This package allows the user, who uses Okta with AWS today, to authenticate with Okta, use that to authenticate to AWS, and then pulls down temporary credentials (access key and secret key) for interacting with the AWS APIs. This allows for users to have access to AWS APIs without long-lived API keys stored on their dev systems. This helps protect the AWS resources as the keys are only valid for at most an hour so an unintended disclosure or leak has a very short window of risk before the keys become invalid. It also helps by enforcing the idea of continually rotating keys; not so different from what the on-box EC2 experience is like when using IAM Roles for EC2.
If you are using Okta to log in to AWS give it a try today;
pip install aws-okta-keyman
