Descope Native Flows offer an innovative approach to user authentication by embedding login experiences directly within a mobile app's interface, addressing challenges associated with traditional browser-based authentication methods. Unlike conventional methods that involve redirecting users to external browsers, which can cause user friction and branding inconsistencies, Descope's solution ensures a seamless, native-like experience that integrates smoothly with an app's UI. The guide provides detailed instructions on implementing Native Flows in a Kotlin-based application, highlighting benefits such as enhanced session management, token persistence, and the ability to update authentication flows without needing app redeployment. Additional features include deep linking for OAuth and magic links, allowing users to authenticate without leaving the app, and advanced capabilities like dynamically adjusting authentication flows to suit different devices and user journeys. By adopting Descope Native Flows, developers can improve user engagement, reduce abandonment rates, and maintain a flexible, secure authentication infrastructure across both mobile and web platforms.
