Thanks you for your good job!

Do you know Firebase Phone Auth

Hi,

I just read about it. There's one thing that might be a problem, the recaptcha process.

A workaround would be to host the html and JavaScript in Firebase Hosting and load it using StageWebView.

If there's a pure REST API I will try to add it.

Thanks!

In the last hours I have been studying how it works and I almost got it working.

I will explain what I got and what failed:

When you start a Phone Auth, Firebase connects to the Google Identity Toolkit and retrieves a recaptchaToken and a recaptchaSiteKey.

Then Firebase exchanges those with the Google Recaptcha Server for another recaptchaToken. This is where I failed, I wasn't able to find a way to get this new token.

Then you need to send to Google Identity Toolkit the new recaptchaToken and the Phone Number with the country code. You will receive a session id.

Finally you send to another Google Identity Toolkit the verification code and the session id from the previous request and the user gets registered.
