**Mobile SSO** enables seamless authentication across multiple mobile apps, allowing users to log in once and access linked apps without re-authenticating. Like Web SSO, it stores authentication sessions using **shared preferences (Android)** or **keychain (iOS)**. It helps identify an active session and automatically retrieve user data to authenticate users in connected apps. Implementing **Mobile SSO with LoginRadius** enhances **user experience, security, and consistency** across the mobile ecosystem.

This document guides implementing Mobile SSO with LoginRadius for Android and iOS, covering SSO flow and implementation for seamless authentication across mobile apps.

## Common Use Cases for Mobile SSO

1.  **Seamless Multi-App Authentication**: Businesses with multiple mobile apps (e.g., financial services, social platforms, or e-commerce brands) can enable Mobile SSO to let users switch between apps without re-entering credentials.
    
2.  **Improved User Experience and Engagement**: Reducing the number of logins prevents user drop-offs, increasing engagement and retention rates for mobile-first applications.
    
3.  **Enhanced Security & Compliance**: Centralized session management helps enforce security policies while reducing password fatigue.
    
4.  **Faster User Onboarding for Subscription & Membership Apps**: Subscription-based services (e.g., streaming platforms, digital news, or fitness apps) can implement Mobile SSO to allow users to register once and access multiple apps without repeated logins.

## Integration Guide

This section provides a step-by-step guide and code snippets for integrating **Mobile SSO** into **Android** and **iOS** applications.

-   ### Android Implementation
    
-   ### iOS Implementation
    

With the [LoginRadius Android SDK](https://www.loginradius.com/docs/sdk/mobile-sdk/android-library/), you can enable Mobile SSO across multiple Android apps, allowing users to log in once and seamlessly switch between apps without re-authenticating.  
SSO enables a single identity for each customer, allowing seamless navigation across all your Android apps with one social ID.

Follow the steps to integrate shared authentication sessions and provide a unified, secure login experience.

-   ### Android Manifest Configuration
    
-   ### Add Login Functionality
    
-   ### SSO Token Management
    
-   ### Add Logout Functionality
    

Add the sharedUserId key and its value to your Android Manifest after the package tag:

```
android:sharedUserId="com.example"
```

## Best Practices

-   **Secure Token Storage:** Use Shared Preferences (Android) and Keychain (iOS) for safe authentication token storage.
-   **Manage Sessions Properly:** Refresh and validate tokens to maintain seamless and secure login.
-   **Ensure Cross-App Consistency:** Implement a unified SSO approach across all linked apps.
-   **Clear Sessions on Logout:** Remove tokens from all apps when users log out.
-   **Optimize Security & Performance:** Enforce token encryption, expiration policies, and fast authentication.
