Which type of Authentication does NOT rely on physical attributes?

Type I authentication, often referred to as something you have, typically involves tokens or cards that provide access based on possession rather than physical attributes of the user. This method does not require any biometric verification such as fingerprints or iris scans, which are characteristics associated with individual physical attributes.

In contrast, the other types of authentication mentioned rely on different methods. Type II includes something you know, such as passwords or PINs, while Type III encompasses biometric methods that analyze physical traits—meaning they do rely on physical attributes. Type IV can involve behavioral biometrics or similar methods but still hinges on identifying unique physical characteristics.

Understanding these distinctions is crucial in identifying the right kind of authentication technique for various scenarios, especially when considering security architecture and vulnerability assessments.
