AWS Security Token Service

AWS Security Token Service (STS) is a cloud-based tool that temporarily grants secure access to AWS resources. Instead of sharing long-term passwords or access keys, organizations can issue short-term, limited permissions to users or applications. This enhances security by reducing the risk if credentials are compromised, and allows flexible control over who can do what and for how long. Essentially, STS acts as a secure gatekeeper, managing temporary access to sensitive cloud services efficiently.
