Hi NatarajanTulasi-6244,

Welcome to our Microsoft Q&A platform!

I tested the demo you provided, but did not get the error "File /outh2redirect does not exist". Besides, to redirect the url to the app, try to override OpenUrl in AppDelegate.cs.

public override bool OpenUrl(UIApplication application, NSUrl url, NSDictionary options)  
{  
    var uri = new Uri(url.AbsoluteString);  
    var googleDriveInstance = GoogleDriveSingelton.GetInstance;  
    googleDriveInstance.auth?.OnPageLoading(uri);  
  
    return true;  
}  

Then you modify the scope in GoogleConfig as follows:

public static string scope = "https://www.googleapis.com/auth/userinfo.email";  

Now you can get the account logged in.

private async void Auth_Completed(object sender, AuthenticatorCompletedEventArgs e)  
{  
    if (e.IsAuthenticated)  
    {  
        var request = new OAuth2Request("GET", new Uri("https://www.googleapis.com/oauth2/v2/userinfo"), null, e.Account);  
        var response = await request.GetResponseAsync();  
        string account_info = await response.GetResponseTextAsync();  
    }  
}
