How to Get SHA-1 & SHA-256 Keys for Firebase | Android Studio & Keytool Methods

In this tutorial, you’ll learn *how to get SHA-1 and SHA-256 keys* for your Android app to integrate with *Firebase**, using both **Android Studio* and the **Keytool command-line method**. These keys are essential for enabling Firebase Authentication features like **Google Sign-In**, **Phone Auth**, and more. Whether you’re building a new Flutter, Kotlin, or Java Android app, this step-by-step guide will show you how to retrieve your app’s *digital fingerprints* the right way. --- 📌 Why SHA-1 & SHA-256 Are Important? Firebase requires the *SHA-1* and *SHA-256 certificate fingerprints* to verify your app’s authenticity and to enable features like: Google Sign-In Authentication Dynamic Links App Invites Phone Authentication Android App Integrity Firebase ML --- 🔧 Methods Covered in This Tutorial: #### ✅ *Method 1: Using Android Studio* 1. Open your Android project in Android Studio. 2. Navigate to: ``` Gradle - Your Project - Tasks - android - signingReport ``` 3. Double-click on `signingReport`. 4. SHA-1 and SHA-256 fingerprints will appear in the *Run* window for each build variant (debug/release). #### ✅ *Method 2: Using Keytool (Command Line)* 1. Open a terminal (or CMD on Windows). 2. Run the following command: ``` keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android ``` On Windows, use the full path: `C:\Users\YourUsername\.android\debug.keystore` 3. SHA-1 and SHA-256 keys will be displayed in the output. --- 💡 Pro Tips: Always use the **correct keystore**: Use `debug.keystore` for development. Use your *release keystore* for production apps. Add both SHA-1 and SHA-256 keys to your *Firebase project settings* under Android App Registration. If you're using **Flutter**, you can still follow these steps from your Android module folder. --- 🔥 Don’t forget to: ✅ Like ✅ Comment ✅ Subscribe for more Android & Firebase tutorials! 📥 Drop your questions below if you face any issues getting your keys. #SHA1 #SHA256 #Firebase #AndroidStudio #Keytool #FirebaseAuth #FlutterFirebase #AndroidDevelopment #FirebaseSetup #GoogleSignIn #SHAkeys #AndroidStudioTips
