Now in console of Firbase, click on Auth section.
On Sign-in method tab, In Google signin method enable that and Save it.

8) Install the required plugins in your Cordova project.

# Plugin for  build info (app name, ID, etc) to OAuth widget.
cordova plugin add cordova-plugin-buildinfo --save
# This Plugin is to handle Universal Links (Android app link redirects)
cordova plugin add cordova-universal-links-plugin --save
# This Plugin is to handle opening secure browser views on iOS/Android mobile devices
cordova plugin add cordova-plugin-browsertab --save
# This one is to handle opening a browser view in older versions of iOS and Android
cordova plugin add cordova-plugin-inappbrowser --save
# This is to handle deep linking through Custom Scheme for iOS
# Add *com.firebase.cordova* In a iOS bundle ID of your app.
cordova plugin add cordova-plugin-customurlscheme --variable \
    URL_SCHEME=com.firebase.cordova --save

9) Add this in config of Cordova xml file of config, DYNAMIC_LINK_DOMAIN for domain in step -3c.

An example: 

<universal-links>
    <host name="xyz123.app.goo.gl" scheme="https" />
    <host name="app.firebaseapp.com" scheme="https">
        <path url="/__/auth/callback"/>
    </host>
</universal-links>

10) To add in your project: 

angular.module('app.controllers.login', ['firebase'])
.controller('LoginController', LoginController);

function LoginController($scope, $firebaseAuth) {
var prov = new firebase.auth.GoogleAuthProvider();
// for Facebook -> prov = new firebase.auth.FacebookAuthProvider();

firebase.auth().signInWithRedirect(prov).then(function() {
        return firebase.auth().getRedirectResult();
      }).then(function(response) {
      console.log("User Details: ", response.user)
     })
}

Above firbase auth will return the object with the user details like name, email, phone, profile pic and further details of the user.
