Firebase Phone Auth + Google Enterprise reCAPTCHA

[mmoraga]

I've been using Firebase phone Auth to auhtenticate users in my app. Sometimes the SMS message is dropped silently by Google and no error message is sent. After talking to Google Support they suggested I enable Google Enterprise reCAPTCHA SMS Defence instead, as that has more configuration options, and I would also see logs for when a request has been blocked.

Does your library support https://cloud.google.com/recaptcha/docs/overview ?

The setup looks very similar to the regular Firebase phone auth, and the different Entitlements required seem to already be provided by react-native-firebase.

Trying to authenticate by just conifguring the recaptcha key in the Firebase dashboard I however get this error:

[auth/unknown] The reCAPTCHA SDK is not linked to your app

Have I completely misunderstood this or is this just a config error?

I'm currently using @react-native-firebase/auth": 21.7.1

I believe this is how you do it - https://github.com/GoogleCloudPlatform/recaptcha-enterprise-react-native
