Temporary Security Credentials (Short‑lived Tokens)

Temporary security credentials are short‑lived authentication tokens that a system issues instead of giving a user or service a permanent password or key. The token carries a set of permissions and an expiration time, after which it cannot be used any longer. By design the credential lives only for minutes or hours rather than years, so even if it is intercepted it quickly becomes useless.

Because the window of validity is narrow, temporary credentials dramatically lower the risk that a compromised secret can be abused. They also make it easier to practice least‑privilege access: an identity can request exactly the rights needed for a particular task and receive a token that expires when the task finishes. This flexibility lets administrators automate role switching for applications, container workloads, or mobile devices without having to embed permanent keys in code.

You will see temporary security credentials most often in cloud platforms that offer identity services, such as when an application assumes a role, a federated user signs in through an external provider, or an automated job requests limited‑time access to storage. In each case the system hands back a short‑lived token that the caller presents to other services, and the token is automatically rejected once its timeout passes.
