I had the same problem while integrating iOS SDK.

If google has same architecture and classes of the firebase SDK across languages, this solution might work for you.

Auth.auth().settings?.isAppVerificationDisabledForTesting = true

Answer 2

 firebase.initializeApp(firebaseConfig);
  // Create a Recaptcha verifier instance globally
  // Calls submitPhoneNumberAuth() when the captcha is verified
  window.recaptchaVerifier = new firebase.auth.RecaptchaVerifier(
    "recaptcha-container",
    {
      size: "invisible",
      callback: function(response) {
        submitPhoneNumberAuth();
      }
    }
  );

Answer 3

use size: "normal" to size: "invisible"

 window.recaptchaVerifier = new firebase.auth.RecaptchaVerifier(
    "recaptcha-container",
    {
      size: "invisible",
      callback: function(response) {
        submitPhoneNumberAuth();
      }

  );

Answer 4

Firebase provides two properties for captcha size

1. Normal - which is visible and captcha code visible to the user and manually perform the captcha process.
2. Invisible - which is invisible to the user, automated captcha process, and code will auto render in DOM.

window.recaptchaVerifier = new firebase.auth.RecaptchaVerifier(
    "recaptcha-container", {
        size: "invisible"
    }
);

Answer 5

You can't remove captcha verification using default authentication.

Use anonymous authentication to avoid captcha letters to appear. Also anonymous authentication is more simpler than Firebase Authentication default authentication.

Usage:

firebase.auth().signInAnonymously().catch(function(error) {
  // Handle Errors here.
  var errorCode = error.code;
  var errorMessage = error.message;
  // ...
});
