ios requires reCAPCHA every time w/ firestore auth (Flutter)

问题

I am using phone verification in my flutter app. My goal is to have the following flow: 1. user enters phone number 2. user is sent verification code 3. user enters code and is signed in. On android, that is the flow I get. On ios, however, it goes 1. user enters phone number 2. reCAPCHA page opens to make sure I'm not a robot 3. user is sent verification code 4. user enters code and is signed in (this happens on ios emulator). I want to get rid of the reCAPCHA page. Some people recommended that I turn on "remote-notifications", so I tried to do this in Xcode by adding it as a "capability" to my runner, and now my Info.plist includes

<key>UIBackgroundModes</key>
    <array>
        <string>remote-notification</string>
    </array>

Which seems right. However, this did not fix the issue, and I am still faced with the capcha.

Version of firebase auth:

firebase_auth: 0.15.4

回答1:

This happens to be in Android as well. I get the reCaptcha opened before I can enter my verification code.

Here is the solution for my problem in Android https://github.com/FirebaseExtended/flutterfire/issues/4189#issuecomment-741711350

Steps made by @Omrankabalan

Go to https://console.cloud.google.com/

If you have a Firebase project you can open in from here

Then select All tab and choose your existing project

Then go to API & Services => Library Search for 'Android Device Verification'

Enable it

In Firebase make sure to add SHA-256 In Project Settings

Test it on a real device

You will need to setup Silent Push Notification for iOS.

Referencing this document: https://firebase.google.com/docs/auth/ios/phone-auth

You will see there are 2 strategies when authorizing Phone Numbers: reCaptcha (to verify you are not a robot) and Silent Push Notifications.

There are additional configurations but in summary:

In Xcode, enable push notifications for your project.
Upload your APNs authentication key to Firebase.
