Launchtoday provides a centralized authentication system through a React Context provider which you can find here. This context manages all authentication flows, user sessions, and authentication state throughout your application. You can find an example of consuming the auth context in the login screen implementation here.

​
Auth Context Provider

The authentication context is implemented using React’s Context API and provides a comprehensive set of methods and state for handling user authentication. The provider is already configured in your application’s root component, making authentication services available throughout your app.

​
Available Methods

The context exposes several authentication methods: 
// Sign in methods
signInWithApple(): Promise<void>    // Handles Apple authentication flow
signInWithGoogle(): Promise<void>   // Handles Google OAuth flow
signInWithEmail(email: string): Promise<void>  // Initiates Magic Link authentication

// Session management
signOut(): Promise<void>            // Signs out the current user
deleteAccount(): Promise<void>      // Deletes the user's account

// State management
user: User | null                   // Current user information
loading: boolean                    // Authentication loading state

​
Authentication Flows

​
Apple Sign In

The signInWithApple method handles the complete Apple authentication flow:
  • Requests user consent through Apple’s native UI
  • Manages identity tokens and nonce validation
  • Creates or updates the user profile in Supabase
  • Establishes the authenticated session

​
Google Sign In

The signInWithGoogle method manages OAuth authentication:
  • Initiates the OAuth flow through a browser
  • Handles redirect and token management
  • Processes the authentication response
  • Creates or updates the user profile
The signInWithEmail method implements passwordless authentication:
  • Sends a magic link to the provided email
  • Handles email redirect
  • Establishes the authenticated session

​
Session Management

The Auth Context automatically manages user sessions:
  • Persists authentication state
  • Handles token refresh
  • Manages session expiration
  • Synchronizes state across the app

​
Error Handling

The authentication methods include comprehensive error handling:
  • User cancellation handling
  • Network error management
  • Invalid token handling
  • Session expiration handling

Next Steps

With the authentication context in place, you can implement specific authentication providers:
