AWS Identity Access Management AWS STS Icon

AWS Security Token Service (STS) is like a temporary ID card provider for your AWS account. Instead of giving users direct, long-term access to your AWS resources, you use STS to create temporary security credentials. This is very useful for granting limited-time access to specific resources, improving security by reducing the risk of long-term compromised credentials, and enabling applications to securely access AWS services without needing long-lived access keys.
