reCAPTCHA site key configuation

[ericq]

Thanks so much for the work.

The phone number login requires reCAPTCHA support. what site-key is used now? how can I replace it with my own site key so we can monitor if there is spamming related.

In additon, the document was not clear about how the related configuration about reCAPTCHA behavior - silent etc.

sorry. maybe this was an invalid question. the firebase docs here https://firebase.google.com/docs/auth/web/phone-auth
"You don't need to manually set up a reCAPTCHA client; when you use the Firebase SDK's RecaptchaVerifier object, Firebase automatically creates and handles any necessary client keys and secrets.". Thus I don't think there is a need to config a reCAPTCHA key here.
