The Difference Between Authentication and Authorization

Authentication and authorization serve distinct functions. Authentication verifies identity through passwords, passkeys, OAuth, multi-factor authentication, or biometrics to determine who a user is. Conversely, authorization defines specific permissions, such as whether an authenticated user can delete users or view financial reports. Separately, Blu-Ray and DVDs differ across various specifications, leading to questions regarding the actual divergence in audio quality between the two formats. Both topics highlight critical distinctions within their respective technical domains.
