Firebase phone Authentication failes

Question

I wanted to do Firebase Login using Phone Auth. As I am developing and I don't have an access to device & Apple developer account, so I went to implement this feature using

reCAPTCHA verification

but I get this following error

{"error":{"code":403,"message":"Requests from this ios client application are blocked.","errors":[{"message":"Requests from this ios client application are blocked.","domain":"global","reason":"forbidden"}],"status":"PERMISSION_DENIED"}}

I have implemented that as it has been shown in the documentation.

Below is the code from AppDelegate.swift:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    FirebaseApp.configure()
    return true
}

// For iOS 9+
func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any]) -> Bool {
    if Auth.auth().canHandle(url) {
        return true
    }
    return false
    // URL not auth related, developer should handle it.
}

Below is the code from ViewController.swift:

@IBAction func didTapSignUp(_ sender: Any) {
    PhoneAuthProvider.provider().verifyPhoneNumber("+919637892151", uiDelegate: nil) { (verificationId, error) in
        if let error = error {
            // It always comes here
            print(error.localizedDescription)
        }
        if let verificationId = verificationId {
            print(verificationId)
            UserDefaults.standard.set(verificationId, forKey: "authVerificationID")
        }
    }
}

Please update your question to include the associated code and google plist file so that we can try to assist — Jake, Jun 27 '18 at 13:11
@Jake I have added the code from AppDelegate and ViewController file. — Anirudha Mahale, Jun 27 '18 at 14:17
Have you added the custom URL schemes in your app configuration and the google plist file? — Jake, Jun 27 '18 at 14:53
It should. It sounds like your plist and your url schemes aren’t right. You’re getting an error saying you don’t have permission to venture to that url. Re-read the documentation and check that part step by step — Jake, Jun 27 '18 at 16:00
It may be some restrictions in your API key. Try to check that in the Google Cloud Console. — bojeil, Jun 29 '18 at 18:12

I followed this answer and it works.

"set the API key Key restriction in Google Console to NONE"

I'm perplexed though because what is the purpose of it if only NONE works?

This is not the correct solution. You shouln't remove your key security. Unfortunately there is not a clean solution because it looks like a Google Auth issue. – FrizzTheSnail Jul 20 '22 at 10:57
@FrizzTheSnail "This is not the correct solution" and "Unfortunately there is not a clean solution" doesn't resolve the problem – Lance Samaria Jul 20 '22 at 15:25
@FrizzTheSnail From Google Docs: "*This flow also requires your **API Key to be unrestricted** or allowlisted*". Read the reCAPTCHA section https://firebase.google.com/docs/auth/android/phone-auth. Even Google itself says it. – Lance Samaria May 19 '23 at 00:16
