Installation

cordova plugin add cordova-plugin-firebase-authentication

Use variables IOS_FIREBASE_POD_VERSION and ANDROID_FIREBASE_BOM_VERSION to override dependency versions for Firebase SDKs:

$ cordova plugin add cordova-plugin-firebase-authentication \
--variable IOS_FIREBASE_POD_VERSION="9.3.0" \
--variable ANDROID_FIREBASE_BOM_VERSION="30.3.1"

To use phone number authentication on iOS, your app must be able to receive silent APNs notifications from Firebase. For iOS 8.0 and above silent notifications do not require explicit user consent and is therefore unaffected by a user declining to receive APNs notifications in the app. Thus, the app does not need to request user permission to receive push notifications when implementing Firebase phone number auth.

Adding required configuration files

Cordova supports resource-file tag for easy copying resources files. Firebase SDK requires google-services.json on Android and GoogleService-Info.plist on iOS platforms.

1. Put google-services.json and/or GoogleService-Info.plist into the root directory of your Cordova project
2. Add new tag for Android platform

<platform name="android">
    ...
    <resource-file src="google-services.json" target="app/google-services.json" />
</platform>
...
<platform name="ios">
    ...
    <resource-file src="GoogleService-Info.plist" />
</platform>
