Generate Debug Certificate

You need to generate 2​ signing certificates​ for the google sign-in feature. Debug certificate is required for testing purposes. If you want to test google signing during development, then you should follow the steps. Otherwise, you can ignore it.

To generate a debug certificate, run this command on your terminal from your app root directory.

Mac	Windows
keytool -list -v \ -alias androiddebugkey -keystore ~/.android/debug.keystore	keytool -list -v \ -alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore

If this command doesn’t work, then go to this link and copy the debug command from there according to your os.

Use ​android as a debug password when the terminal asks for a password.
