\'This App Is Not Authorized to Use Firebase Authentication\': How to Solve the Error After an Android Studio Upgrade?

"This App Is Not Authorized to Use Firebase Authentication" Error in Firebase Console

Problem:

Firebase Authentication was functioning without issues. However, after an Android Studio upgrade, the debug build began to fail, displaying the following error message:

D/PhoneAuthActivity( 7392): signInWithCredential:failure:com.google.firebase.auth.FirebaseAuthException: This app is not authorized to use Firebase Authentication. Please verify that the correct package name and SHA-1 are configured in the Firebase Console. [ App validation failed ].

This error occurred despite not making any changes to the code after a successful login.

Solution:

Updated (May 12th, 2022):

Obtain the SHA-1 and SHA-256 certificate fingerprints from the Play Store Console:

Play store Console > Your project > Release > Setup > App integrity

[Image: SHA-1 and SHA-256 fingerprints from Play Store Console]

Add both SHA-1 and SHA-256 fingerprints to your Firebase app:

Firebase Console > Your project > Settings of the app > Add Fingerprint

[Image: Fingerprints added to be in Firebase console]

Additional Considerations:

Include the local SHA-1 and SHA-256 values. Use the command ./gradlew signingReport to get them. For more information, refer to this document.
Phone OTP verification via emulator won't work because it lacks a SIM. Install the app on a mobile device with a SIM.
Verify that the "Enable app verification step" is correctly configured and that Android Device Verification is enabled.
Ensure the correct project is selected from the drop-down menu when enabling Android Device Verification.
Both SHA-1 and SHA-256 fingerprints must be registered in the Firebase project.
Use the most recent version of the google-services.json file after making all the changes.

How does the JVM manage garbage collection across different platforms?Apr 28, 2025 am 12:23 AM

Why can Java code run on different operating systems without modification?Apr 28, 2025 am 12:14 AM

Java code can run on different operating systems without modification, because Java's "write once, run everywhere" philosophy is implemented by Java virtual machine (JVM). As the intermediary between the compiled Java bytecode and the operating system, the JVM translates the bytecode into specific machine instructions to ensure that the program can run independently on any platform with JVM installed.

Describe the process of compiling and executing a Java program, highlighting platform independence.Apr 28, 2025 am 12:08 AM

The compilation and execution of Java programs achieve platform independence through bytecode and JVM. 1) Write Java source code and compile it into bytecode. 2) Use JVM to execute bytecode on any platform to ensure the code runs across platforms.

How does the underlying hardware architecture affect Java's performance?Apr 28, 2025 am 12:05 AM

Java performance is closely related to hardware architecture, and understanding this relationship can significantly improve programming capabilities. 1) The JVM converts Java bytecode into machine instructions through JIT compilation, which is affected by the CPU architecture. 2) Memory management and garbage collection are affected by RAM and memory bus speed. 3) Cache and branch prediction optimize Java code execution. 4) Multi-threading and parallel processing improve performance on multi-core systems.

Explain why native libraries can break Java's platform independence.Apr 28, 2025 am 12:02 AM

Using native libraries will destroy Java's platform independence, because these libraries need to be compiled separately for each operating system. 1) The native library interacts with Java through JNI, providing functions that cannot be directly implemented by Java. 2) Using native libraries increases project complexity and requires managing library files for different platforms. 3) Although native libraries can improve performance, they should be used with caution and conducted cross-platform testing.

How does the JVM handle differences in operating system APIs?Apr 27, 2025 am 12:18 AM

JVM handles operating system API differences through JavaNativeInterface (JNI) and Java standard library: 1. JNI allows Java code to call local code and directly interact with the operating system API. 2. The Java standard library provides a unified API, which is internally mapped to different operating system APIs to ensure that the code runs across platforms.
