AWS Identity Access Management AWS STS Alternate Icon

AWS Identity Access Management (IAM) lets you control who can access your AWS resources. AWS Security Token Service (STS) is an IAM alternate that provides temporary security credentials, offering fine-grained control and enhanced security. You can use STS to grant temporary access to users, applications, and services without sharing long-term access keys, improving security posture. It is often used for applications needing temporary access or federating identities from other systems to AWS.
