Firebase.AppCheck.FirebaseAppCheck

Firebase App Check object.

Summary

App Check helps protect your API resources from abuse by preventing unauthorized clients from accessing your backend resources.

With App Check, devices running your app will use an AppCheckProvider that attests to one or both of the following:

  • Requests originate from your authentic app
  • Requests originate from an authentic, untampered device

Properties
DefaultInstance

SetAppCheckProviderFactory(IAppCheckProviderFactory factory)
void
Installs the given IAppCheckProviderFactory, overwriting any that were previously associated with this FirebaseAppCheck instance.

Public functions
GetAppCheckTokenAsync(bool forceRefresh)
System.Threading.Tasks.Task< AppCheckToken >
Requests a Firebase App Check token. This method should be used ONLY if you need to authorize requests to a non-Firebase backend. Requests to Firebase backends are authorized automatically if configured.
