AWS Security Token Service (STS) AssumeRole

See more AWS Security Token Service Examples

Returns a set of temporary security credentials that you can use to access AWS resources. These temporary credentials consist of an access key ID, a secret access key, and a security token. Typically, you use AssumeRole within your account or for cross-account access. Go
