Authentication vs. authorization: what you need to know

Authentication and authorization are distinct but complementary processes crucial to user identity and access management in app security architecture. Authentication verifies a user's identity through different factors such as passwords, biometrics, or devices, ensuring the user is who they claim to be before access is granted. This process has evolved from single-factor authentication to more secure methods like multi-factor authentication, including two-factor authentication and just-in-time authentication for sensitive tasks. Authorization, on the other hand, determines what actions a user is permitted to undertake within an app after successful authentication, using models like role-based, attribute-based, and rule-based access control. While authentication is a user-visible process that allows adjustments to settings, authorization often operates in the background, with permissions managed by the organization. Together, these processes ensure secure access management, where session management plays a role in maintaining user context and permissions data. Stytch offers solutions to enhance these processes by providing passwordless authentication options and breach-resistant password systems, aiming to balance security with user experience.
