Protection for your data and your customers
App Check is an additional layer of security that helps protect access to your services by attesting that incoming traffic is coming from your app, and blocking traffic that doesn't have valid credentials. It helps protect your backend from abuse, such as billing fraud, phishing, app impersonation, and data poisoning.
Broad platform support that you can tailor to your needs
App Check supports Android, iOS and Web out of the box. For customers that want to support more platforms, you can integrate your own attestation provider with App Check's custom capabilities.
Integration with Firebase products, or your own backend
App Check works with Firebase products, like Cloud Firestore, Realtime Database, Cloud Storage for Firebase, Cloud Functions for Firebase, Google Cloud products like Cloud Run and Apigee, or your own custom API endpoints.
Fast, flexible and reliable
With a convenient UI and SDKs for web, iOS, and Android, you can get up and running with App Check with just two lines of code. App Check complements existing security solutions like Firebase Auth and Security Rules to provide even stronger security. And for developers with more sophisticated needs, App Check is certified under major compliance and security standards.
