What are access control credentials?

Access control credentials refer to the specific items, knowledge, or characteristics that allow an individual to prove their identity and gain access to a system or location. These credentials can take various forms, including physical items like access cards, knowledge-based elements such as passwords or PINs, and even biometrics like fingerprints or retina scans, which are unique to an individual.

This understanding of credentials is critical in electronic access control systems as they serve as the primary means of validating an individual's right to enter secured areas or access sensitive information. In contrast, the other options relate to different aspects of security and access control but do not capture the fundamental concept of what credentials represent in this context. For instance, items an organization possesses focuses on physical possessions rather than the verification of identity, features of a security camera pertain to surveillance rather than access, and methods of controlling boundaries refer to the mechanisms applied rather than the identifiers that allow access. Each of these choices lacks the specific focus on individual possession or uniqueness that defines access control credentials.
