For those who tried to emulate their app in AVD and prompted for "Enable app verification" or "Error", add SHA 1 fingerprint to your project in firebase > project settings > Add fingerprint and then Connect your real phone with USB debugging and emulate it on real device. This wont work on Emulator.

Hello Taimoor, in this tutorial I have come across with this error: "This app is not authorized to use Firebase Authentication. Please verify that the correct package name and SHA-1 are configured in the Firebase console. App validation failed. Is app running on a physical device?" Quick note that I have enabled phone authorization in firebase console. My app is connected to the firebase from the android studio all the dependencies are added. I would very much appreciate if you could help.Thanks.

Thanks first. Is there a way to accept only the phone number on which the app is installed. The reason is not to allow users to enter data on behalf of someone else by spoofing??

I had a problem, when I was waiting for my code verification, when this is was sended to me twice with different phone numbers and I did exactly what you did, I checked my code and there is no point where I send the code verification twice. Becase this, I saw a message exception from google and it shows "this device has been blocked due to.." and this is because I was doing test, how can I unblock this? will this device block be forever? please I want to know these 2 questions, finally.. thanks so much for your help
