Answer 1

You can remove reCaptcha by Enabling the Android Device Verification API in Your Project on google cloud console. You can do that by Adding Your Project there.

After that you should also add SHA-256 key in Your Firebase Project in Project Setting.

Now there will be no reCaptchaa to verify to that your are not a robot.
