Overview
Firebase App Check helps protect Firebase backend resources from abuse by verifying that requests originate from legitimate, unmodified apps. It works alongside other Firebase services to prevent unauthorized access, such as billing fraud or phishing attacks. By integrating app attestation with safety net, device check, or reCAPTCHA, it ensures only trusted apps can access your services. Available across Android, iOS, Web, macOS, and Windows, it enhances security without requiring significant code changes. Ideal for apps handling sensitive data or monetized services.
