Authenticating Your Client

Certain Google Play services (such as Google Sign-in and App Invites) require you to provide the SHA-1 of your signing certificate so we can create an OAuth2 client and API key for your app. To get your SHA-1, follow these instructions:

To get the debug certificate fingerprint:

Method 1:

Change your app configuration to Gradle project (signingReport) then click run button in Android Studio.

Android SHA-1

This process prints the fingerprint to the Run tab at the bottom.

Method 2:

Open a terminal and run the keytool utility provided with Java to get the SHA-1 fingerprint of the certificate.

Mac/Linux

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

Windows

keytool -list -v -keystore %USERPROFILE%/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

Android SHA-1

To get the release certificate fingerprint:

keytool -list -v -keystore <your_keystore_name> -alias <your_alias_name>

where:
<your_keystore_name> is the path and name of the Keystore, including the .keystore extension.
<your_alias_name> is the alias that you assigned to the certificate when you created it.
