Select your Provider

Providers are platform-specific adapters that handle the authentication flow with your identity provider (e.g., Auth0). They abstract away the differences between web browsers and mobile platforms.

  • SDKs provide the FastAuthClient and FastAuthSigner classes for authentication and signing.
  • Providers handle platform-specific authentication (browser redirects vs. native app flows).

JavaScript Provider​

The JavaScript Provider is designed for web browsers and works with the Browser SDK or React SDK. It handles OAuth redirects and token management.

For detailed documentation, see the JavaScript Provider Getting Started and JavaScript Provider API.

React Native Provider​

The React Native Provider is designed for iOS and Android mobile applications. It uses native authentication flows and secure credential storage.

For detailed documentation, see the React Native Provider Getting Started and React Native Provider API.
