What does it do?#
App Check helps protect your backend resources (such as Cloud Storage) from abuse (such as billing fraud or phishing).
With App Check, devices running your app will use an app identity attestation provider to certify it is indeed your authentic app, and may also check that it's running on an authentic, untampered device. This certification is attached to every request your app makes to your Firebase backend resources.
App Check currently supports Cloud Storage, Realtime Database, and Cloud Functions, with more Firebase products coming soon.
Note: App Check may not protect against certain abuse vectors when paired with a CDN.
