Disabling Captcha for phone number authentication

[davebanguilan]

I was able to add the SHA fingerprint both SHA-1 and SHA-256. But when I am testing it, the app opened chrome for a bit (It says verifying for Captcha) then it redirected back to my app. How can I avoid the Captcha part?

Maybe this helps you: https://stackoverflow.com/a/65144360/6731412

Also, need to perform additional steps: Firebase Project Settings > App check > and Register firebase project in SafetyNet and Play Integrity register with default time token 1 hour.

I have not tested it myself yet. There is also an open issue for Firebase AppCheck: #177

@robingenz we want to activate integrity check on the app . Do you maybe already have some small instruction how to update from old version to new one so that the new sdk will be used and what exactly we should do on Firebase/Google Cloud console this to happen?

Is the step of adding

implementation 'androidx.browser:browser:1.2.0' needed? It seems very little info in docs and tickets in this regards with your library .

@robingenz No I don't want to use app-check. I don't know how to make phone authentication to work. because Safety Net checks are obsolete. And now Phone Verification has to be done other way.

@robingenz #293 (comment) here you say that it's just about SDK and new version solves the problem , but it seems it is not.

With updated Package we are getting this.

I don't know how to make phone authentication to work.

Nothing special here. Just follow the setup guide.

We also provide an example:

const signInWithPhoneNumber = async () => {
  return new Promise(async resolve => {
    // Attach `phoneCodeSent` listener to be notified as soon as the SMS is sent
    await FirebaseAuthentication.addListener('phoneCodeSent', async event => {
      // Ask the user for the SMS code
      const verificationCode = window.prompt(
        'Please enter the verification code that was sent to your mobile device.',
      );
      // Confirm the verification code
      const result = await FirebaseAuthentication.confirmVerificationCode({
        verificationId: event.verificationId,
        verificationCode,
      });
      resolve(result.user);
    });
    // Attach `phoneVerificationCompleted` listener to be notified if phone verification could be finished automatically
    await FirebaseAuthentication.addListener(
      'phoneVerificationCompleted',
      async event => {
        resolve(event.result.user);
      },
    );
    // Start sign in with phone number and send the SMS
    await FirebaseAuthentication.signInWithPhoneNumber({
      phoneNumber: '123456789',
    });
  });
};

If this does not work, please create a bug report. The error can have different reasons, see this SO thread.

Dear @robingenz everything was working prior the Integrity Check problem. The most unclear part is Step N4

See [Enable app verification](https://firebase.google.com/docs/auth/android/phone-auth#enable-app-verification) and follow the instructions to enable app verification correctly.

Your problem is not directly related to the plugin, but to the configuration of the Firebase SDK. Please reach out to the Firebase team. I can only provide limited support for the plugin. Again, i recommend taking a look at this SO thread.
