Realtime Database


  • changed The way you install and initialize the SDK has changed and most APIs have been renamed. When you decide to upgrade, please see the iOS Migration Guide, Web Migration Guide, or Android Migration Guide for details.
  • changed Node.js / Java server SDKs:
    • Token minting and verification for Firebase Authentication is now built into the server SDKs themselves instead of in separate token minting libraries.
    • All of the existing authentication methods have been removed. Instead, use the databaseAuthVariableOverride option (Node.js) or setDatabaseAuthVariableOverride() method (Java) when initializing the SDK. See here for more details.
    • Use the Web Migration Guide or Android Migration Guide to help you update your Node.js or Java code to the latest APIs.
  • issue General:
    • Limited profile data extracted from federated providers (e.g. doesn’t include the Twitter username).
    • Workaround where possible, extract this information from the 3rd party SDKs.
  • issue Firebase Android SDK:
    • FirebaseUser#linkWithCredential() may invalidate a user's credentials.
      • Description: After calling linkWithCredential() with a credential that is not an EmailAuthCredential, sometimes consecutive calls on the user object may throw an Exception: FirebaseException (An internal error has occurred. [ TOKEN_EXPIRED ]).
      • Workaround Cache the credential used on a linking event, and if this error is thrown, sign the user out after the linking and call FirebaseAuth#signInWithCredential() with the cached credential afterwards.
    • Missing API to start email verification flow.
    • Some Network exceptions are thrown as FirebaseException rather than FirebaseNetworkException.
  • issue Firebase SDK for iOS:
    • sendPasswordResetWithEmail:completion: does not call the completion handler in the main thread as claimed.
    • Workaround:


      [[FIRAuth auth] sendPasswordResetWithEmail:@"user@host.domain"
                                    completion:^(NSError *_Nullable error) {
        dispatch_async(dispatch_get_main_queue(), ^{
      // original completion handler code.


      FIRAuth.auth()?.sendPasswordResetWithEmail("user@host.domain") { error in
      dispatch_async(dispatch_get_main_queue()) {
      // original completion handler code.
    • API reference docs do not contain information about error conditions: see them here.
    • Authentication state is shared between different apps when running on. the iOS Simulator:
      • Description: when running two or more applications that use Firebase Authentication on the same iOS simulator, there is a issue with the iOS keychain that causes the authentication state to be shared across the different applications. This means that if you sign in to an app, and later open a second app, you may find a user to be signed in into it.
      • Workaround: either don't use two different applications with Authentication on the same simulator instance, or manually sign out from the applications between tests.
  • issue Firebase JavaScript SDK:
    • If you change the authdomain configuration of an app while some users are signed in, you have to sign them out and in again in order to use linkWithPopup/Redirect APIs
    • Does not work in Safari private browsing mode.


  • feature Initial release of Cloud Storage. Cloud Storage provides secure file uploads and downloads for your Firebase apps, regardless of network quality. You can use it to store images, audio, video, or other user-generated content. Firebase Storage is backed by Google Cloud Storage, a powerful, simple, and cost-effective object storage service.
  • issue Firebase console: Only project owners can update Firebase Security Rules for Cloud Storage, and only owners and editors can view Storage Security Rules.


  • feature Initial release of Cloud Messaging.

  • issue Firebase C++ SDK:

    • Messages with both a notification and data payload are not delivered to an Android application open in the background.
    • Description: On Android, when the app is open in the background and it receives a message with both a notification and data payload, the message is not delivered to the application.
    • Workaround: In the application's activity, (e.g. NativeActivity), override the onNewIntent(Intent intent) method and pass the intent argument through to the method setIntent(Intent intent)
    • For example:
      public class MyActivity extends NativeActivity {
        onNewIntent(Intent intent) {
      See the quickstart sample for an example of this workaround in action.
