better-auth-tauri-setup

OAuth authentication in a Tauri v2 desktop app is handled by configuring deep link URL schemes to catch browser redirects and using better-auth middleware to persist cookie-based sessions. This ensures the OAuth flow securely returns users to your application with an active session.

Deep link integration for Tauri callbacks works by registering OS-level URL schemes that intercept OAuth redirects from external browsers. When a user authenticates via Google or GitHub, the browser redirects back to the Tauri app using the custom URL scheme to establish the session.

Yes, you can use better-auth with Tauri to achieve persistent cookie sessions on Windows and macOS. The setup requires the @daveyplate/better-auth-tauri plugin alongside client-side fetch overrides to ensure the authentication state persists across both operating systems.

The best way to manage browser-to-app redirects for desktop authentication is using deep-link callback schemes combined with HTTP cookie support. This approach securely bridges the gap between external browser OAuth flows and your desktop application's session management.

Yes, you need specific Tauri plugins including @tauri-apps/plugin-deep-link, @tauri-apps/plugin-http, and @tauri-apps/plugin-opener to configure deep link schemes. These plugins handle URL interception, HTTP requests, and browser opening for the OAuth flow.

Authentication cookies may not persist in a Tauri desktop application if client-side fetch overrides and the @daveyplate/better-auth-tauri plugin are not properly configured. Correct middleware setup is required to ensure session state persists across macOS and Windows environments.
