Which AWS feature grants temporary access to specific AWS resources?

Explanations:

AWS IAM Access Analyzer helps identify resources that can be accessed from outside an account but does not grant temporary access to AWS resources.

Service control policies (SCPs) are used to manage permissions across AWS Organizations but do not provide temporary access to AWS resources.

Access control lists (ACLs) are used for managing permissions on specific resources, primarily in Amazon S3 and VPCs, but do not grant temporary access.

IAM roles are specifically designed to provide temporary access to AWS resources. They allow users or services to assume the role and access specific permissions for a limited time.
