Google Login for unity (NOT Google Play Games services Login)

Hi,

I am building an AR project and are trying to give a GOOGLE LOGIN in Unity . Although there is Google play games plugin for unity but I cannot use that because it's login show google that he is joining for a Game. (as AR is not a game)

I tried using Google Firebase for UNity ( https://firebase.google.com/docs/auth/unity/google-signin ) but I am unable to use it. I created a plugin for Google Sign-In in Android Studio and imported it into the main project and then tried to use that plugin for Google Sign-in. It does not work.

 

Well... even if it isn't a game, you should be able to use the google play games services? Just don't implement leaderboards or achievements (I think you have to create some dummy ones anyway or it won't publish).

Wouldn't that work?

 

Hi, could you solve you problem? I rrally need help with that.
Thanks

 

Hi, can you share your plugin sources?

 

I'm in the same position as OP. I'm building a non-game VR app and would like to have secure Google sign-in. The Google Play Services integration with Unity is not satisfactory because it doesn't provide the necessary information to be able to securely authenticate your backend server (you can't just send the user ID because that can be spoofed). My few hours of research today seem to indicate that there is no way to do this currently via Unity?

 

Hi
I have come across same problem, is there anyone who can help me with solution.

I tried using Google Play Game Services, but the problem with that plugin is that if Play Google Games app is not there on the device, it just direct to play store and callback API is returning false, leaving users clueless as to why Google login fail. Is there a better way to implement google login?

 

You can do that by sending the idtoken to your server and then validating that as described here: https://developers.google.com/identity/sign-in/web/backend-auth
However, I have the problem that the id token is never refreshed during a session using the GooglePlayGames plugin, and it is only valid for a rather short time :-(

 

Guys, look at this discussion, you probably do not need to have endless ID token
http://stackoverflow.com/questions/25686484/what-is-intent-of-id-token-expiry-time-in-openid-connect

 

I don't need it to be endless, but I do need it to be fresh when I get it from the plugin. Not potentially expired like it is now.
In my case, the client uses the id token to authenticate itself to my backend service.

 

Can someone help with this?
Can we use Firebase google sign in in Unity, after all?

Thank you very much.

 

I have put together Unity Google login asset and is now available in asset store @ https://www.assetstore.unity3d.com/en/#!/content/94517. It works with both iOS & Android for now.

 

You can try with this asset http://u3d.as/JR6, include Google, Facebook, Twitter authentication with Firebase.

 

Please checkout my article on this, after suffering 2 weeks, finally I made it work like a charm and decide to publish a tutorial about this:
