Describe the problem

I want to authenticate using phone number OTP only for my react native app I created last week. I'm using latest versions of React Native, Expo and Firebase/auth.

I'm following this document: https://firebase.google.com/docs/auth/web/phone-auth?hl=en&authuser=0&_gl=1*bgntt3*_ga*MTM4ODE1MDc1My4xNzIzMDM5OTgz*_ga_CW55HF8NVT*MTcyMzQyNDc0MC4xMC4xLjE3MjM0MjUwNzIuMzIuMC4w

I've tried using window.recaptchaVerifier and RecaptchaVerifier from firebase/auth but its not supporting in iOS. Error is Can't find 'verify' of undefined.

Steps and code to reproduce issue

const confirmationResult = signInWithPhoneNumber(auth, phoneNumber, applicationVerifier);

applicationVerifier as window.recaptchaVerifier and RecaptchaVerifier from firebase/auth are both resulting error that "Can't find 'verify' of undefined.

What is the best value of applicationVerifier for React Native that can support in both ios and android simulator as well as in real devices. This is mobile only app.

Could you ensure that an update to window is within a useEffect hook, similar to the issue reported here?

If that doesn't solve the problem then could you please provide a standalone test app that reproduces the problem? Thank you!

Oh, I'm sorry, I just noticed you're using React Native and not React JS.

Therefore, some more notes:

You should only use react-native-firebase or firebase but it looks like they're both listed in your dependencies. They are differnet products and will not work in conjunction with one another. Additionally, I believe that react-native-firebase doesn't work with Expo.

ReCaptcha isn't supported in the firebase Auth implementation for React Native, since there isn't a Window or DOM in ReactNative.

Is there a reason you need to use ReCaptcha in this environment? Thanks!
