AppAuth-Android: Secure OAuth 2.0 & OpenID Connect SDK for Android
AppAuth-Android is an open-source client SDK for Android applications to comfortably and securely communicate with OAuth 2.0 and OpenID Connect providers. It simplifies common authentication and authorization flows.
Project Introduction
Summary
AppAuth-Android is a native Android library designed to make integrating with OAuth 2.0 and OpenID Connect identity providers both straightforward and secure. It abstracts away much of the complexity of these protocols.
Problem Solved
Implementing OAuth 2.0 and OpenID Connect flows manually in mobile applications is complex, prone to errors, and can introduce security vulnerabilities. AppAuth-Android provides a robust, well-tested library that follows current best practices.
Core Features
PKCE Support
Supports the latest best practices including PKCE, simplifying secure implementation of the authorization code flow.
System Browser Authentication
Utilizes the system browser for authentication flows, improving security, usability, and single sign-on capabilities.
Token Management
Assists in managing token refreshing and session state with the identity provider.
Id Token Verification (OIDC)
Handles JWA (JSON Web Algorithms) for id_token verification when using OpenID Connect.
Tech Stack
使用场景
AppAuth-Android is suitable for any Android application that requires secure interaction with OAuth 2.0 or OpenID Connect endpoints, such as:
场景一：用户登录与单点登录 (SSO)
Details
Allow users to log into the Android app using their existing accounts from a compatible identity provider (e.g., corporate SSO, public IDP).
User Value
Simplifies user onboarding and provides a familiar, secure login experience, potentially enabling SSO across applications that use the same provider.
场景二：安全访问受保护的API
Details
Obtain access tokens to securely call APIs on behalf of the authenticated user, managing token refresh transparently.
User Value
Ensures that API calls are properly authorized using standard tokens, enhancing security and simplifying token lifecycle management for the developer.
