briefaccess

Briefaccess is a term used informally in information technology and security to describe mechanisms that grant temporary, bounded access to a resource. It covers time-limited authorization, ephemeral credentials, and short-lived sessions designed to reduce exposure of sensitive assets after use.

Typical implementations rely on tokens or links that expire after a defined period, or on sessions that must be renewed or re-authenticated. Examples include expiring API tokens, one-time access links for files, and temporary credentials issued by identity providers or access gateways. These systems often require server-side validation of timestamps, nonce values to prevent replay, and mechanisms to revoke access when the window closes.

Use cases include file sharing with a deadline, remote support sessions, and privileged operations in cloud environments where long-lived credentials pose security risks. In cloud platforms, short-lived credentials are a practical embodiment of the briefaccess principle.

Benefits of briefaccess include reduced risk from leaked credentials, stricter control over how long resources are accessible, and clearer audit trails. Drawbacks include the potential for clock skew to invalidate legitimate sessions, user inconvenience from frequent re-authentication, and added system complexity for token management and revocation propagation.

The term lacks formal standardization. In practice, similar concepts are described as temporary access, time-bound access, expiring tokens, or ephemeral credentials.
