About AWS IAM Role Anywhere support
Using AWS IAM Role Anywhere you can authenticate AWS S3 storage in a secure way using temporary security credentials. You can set up an IAM Role Anywhere in your AWS account and use the necessary certificate and private key to authenticate.
Note:
IAM Role Anywhere is not supported for FortKnox AWS. Also, switching between IAM Role Anywhere and other authentication types such as Access Key is not supported.
