How to Get SHA-1 key in Android Studio for Firebase.

There are two methods of getting SHA-1 key, but First one is not working for Windows user. So, if you are a Windows user then go for 2nd Method.

Update:- On Android Studio Latest version(on 24 Sept 2021) 2020.3.1 for Windows 64-bit (912 MiB), Step 2 will not Work. So, go for Step 3.

1. Using Keytool

Open a terminal and run the keytool the utility provided with Java to get the SHA-1 fingerprint of the certificate. You should get both the release and debug certificate fingerprints.

To get the release certificate fingerprint:

For Windows:-

keytool -list -v \
-alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore

For Mac/Linux:-

keytool -list -v \
-alias androiddebugkey -keystore ~/.android/debug.keystore

Note:- If you are not able to get your SHA-1 key using Keytool then Follow the below Method, in this method you will definitely get your SHA-1 key.

2. Using Gradle’s Signing Report

You can also get the SHA-1 of your signing certificate by Gradle signingReport. But for that, you have to follow some steps.

Step 1: – First of all
=> open your project in Android Studio and open the project.
=>In the project, go to the android/app directory where you find build.gradle file. => Open it.

=> After that Open Android->Tasks->android and Double click on signingReport.
