In the context of IAM, what does a “shorter lifespan” imply?

A "shorter lifespan" in the context of Identity and Access Management (IAM) refers to the duration that a particular message or token is valid before it expires. When messages have a shorter lifespan, it implies that they will expire quickly, meaning they can only be used or valid for a brief period. This is often designed to enhance security since shorter-lived messages minimize the window of opportunity for unauthorized access or misuse. The shorter lifespan helps ensure that if a message or token is intercepted, its limited validity period reduces the risk of it being used maliciously. The proactive expiration of these messages is a key aspect of maintaining secure communications and access management within IAM frameworks.
