Thanks, but not sure I understand?
As I've said, I've followed the guide multiple times exactly

I've been trying to fix this issue for 2 weeks and finally managed to do it.
What helped me was adding tester e-mail addresses in the google play console

I hope it helps!

Hello! I have the following issue when testing on my mobile.

It seems that that I can authenticate, I'm getting an authorization code, but when calling SignInWithGooglePlayGames, it seems that it fails at await AuthenticationService.Instance.SignInWithGooglePlayGamesAsync(authCode). Anybody encountered this issue?

I am facing the same issue and can't seem to move forward with it. Anyone found a resolution to this?

You must build your project at least once and generate a keystore before moving on to the next step. Learn more here

Open a Command Prompt on Windows or Terminal on a Mac

WINDOWS: *Required to have JDK installed

Generate a SHA-1 key by typing the following into your Command Prompt
keytool -list -keystore .android\[yourkeystorename].keystore -v

[If the above fails] Generate a SHA-1 by navigating to your JDK installation folder normally located under C:\Program Files\Java\jdk[version]\bin> using the Command Prompt *depending on your JDK installation

keytool -list -keystore ~/.android/[yourkeystorename].keystore -v

[If the above fails] Generate a SHA-1 by navigating to your JDK installation folder normally located under /Library/Java/JavaVirtualMachines/jdk[VERSION] *depending on your JDK installation using the Terminal

Copy your keystore folder path. This is normally generated when create your keystore

Run the following command:

using GooglePlayGames.BasicApi;

using System.Threading.Tasks;

using Unity.Services.Authentication;

using Unity.Services.Core;

using UnityEngine;

public class GPManager : MonoBehaviour

{

public string Token;

public string Error;

void Awake()

{

PlayGamesPlatform.Activate();

}

async void Start()

{

await UnityServices.InitializeAsync();

await LoginGooglePlayGames();

await SignInWithGooglePlayGamesAsync(Token);

}

//Fetch the Token / Auth code

public Task LoginGooglePlayGames()

{

var tcs = new TaskCompletionSource<object>();

PlayGamesPlatform.Instance.Authenticate((success) =>

{

if (success == SignInStatus.Success)

{

Debug.Log("Login with Google Play games successful.");

PlayGamesPlatform.Instance.RequestServerSideAccess(true, code =>

{

Debug.Log("Authorization code: " + code);

Token = code;

// This token serves as an example to be used for SignInWithGooglePlayGames

tcs.SetResult(null);

});

}

else

{

Error = "Failed to retrieve Google play games authorization code";

Debug.Log("Login Unsuccessful");

tcs.SetException(new Exception("Failed"));

}

});

return tcs.Task;

}

async Task SignInWithGooglePlayGamesAsync(string authCode)

{

try

{

await AuthenticationService.Instance.SignInWithGooglePlayGamesAsync(authCode);

Debug.Log($"PlayerID: {AuthenticationService.Instance.PlayerId}"); //Display the Unity Authentication PlayerID

Debug.Log("SignIn is successful.");

}

catch (AuthenticationException ex)

{

// Compare error code to AuthenticationErrorCodes

// Notify the player with the proper error message

Debug.LogException(ex);

}

catch (RequestFailedException ex)

{

// Compare error code to CommonErrorCodes

// Notify the player with the proper error message

Debug.LogException(ex);

}

}

}

Testing
Check if authentication is working by using Unity Logcat or Android studio Logcat.
You must connect your device to your workstation to view the Logcat.
A successful test will print out the following:

Unity Logcat (example):

Android Studio Logcat (example):

Additionally a visual queue will be displayed upon successful login.

Conclusion
This should get you started logging in to authentication and google play games generating and linking a user id between Google and Unity.

@SebT_Unity Thank you for collating all the information. I want to report that I have been able to get Google Play Games signin working but not the step of Linking it to a Unity Player ID.
When I call SignInWithGooglePlayGamesAsync(authCode) I get the error as in the screenshot. Could you let me know if there is a known fix for this problem? Or else, if your team is looking into it?

wgeorgio · Sep 24, 2023

Is there a way to cache or keep the player logged in either with Google or other authentication?

hanzyusuf · Sep 25, 2023

Finally got it working after a week ! Can't believe it was so simple. I was now under the impression that it isn't possible without publishing the app, but I'm glad I didn't need to publish just to test play game services.

I had followed every single instruction and correctly setup my sha1 key too, and also added tester emails in the api cloud console as well as the testing section (closed testing, open testing, internal testing). The problem was that adding testers here doesn't mean anything, I had to add tester emails within the Play Games Services section. Default emails are already added, but I use another email for my personal device, and hence the problem.

Hope someone benefits from this.

Diredia · Oct 6, 2023

I want to use other scopes like "openid" etc.., so I Added following scope : openid.
And Client App acquire client's auth code via RequestServerSideAccess() then served that code to backend server.
Then backend server get access-token by using auth code.
But ... when backend server send this access-token to endpoint "https://oauth2.googleapis.com/tokeninfo?access_token=",
server can not know user's information(email etc..) irrelevantly of setting scope.
Even server can not get 'Id Token'..

Then how to backend server know user's information to make client account?
