Hi Anders Bjerner,

This is what I am doing so far:

I have use your package to create a login page with google account:

Until this phase, I got Access token, ID, Name, Email from Google account. So then, how can I save those data to database and for next time user click on link "Login with Google" it will automatic login into my Umbraco?

To archive the screen above, I have followed your code:

    @using Skybrud.Social.Google
@using Skybrud.Social.Google.OAuth
@inherits WebViewPage

@{

    // Initialize a new instance of the OAuth client
    GoogleOAuthClient oauth = new GoogleOAuthClient {
        ClientId = "857672463365-n09cg4vfvktua2kvlpq2rvaa7kfku66t.apps.googleusercontent.com",
        ClientSecret = "K5dSWIybdhCCYqZrweq7ZUBE",
        RedirectUri = "http://localhost:62195/"
    };

    // Read some input from the query string
    string code = Request.QueryString["code"];
    string action = Request.QueryString["do"];
    string error = Request.QueryString["error"];


    // Handle the state when the user clicks our login button
    if (action == "login") {

        // Get the redirect URI (if present)
        string redirect = (Request.QueryString["redirect"] ?? "/");

        // Set the state (a unique/random value)
        string state = Guid.NewGuid().ToString();
        Session["Google_" + state] = redirect;

        // Construct the authorization URL
        string authorizationUrl = oauth.GetAuthorizationUrl(state, GoogleScopes.Email + GoogleScopes.Profile, GoogleAccessType.Online, GoogleApprovalPrompt.Force);

        // Redirect the user to the OAuth dialog
        Response.Redirect(authorizationUrl);
        return;

    }

    // Handle if an error occurs during the Google authentication (eg. if the user cancels the login)
    if (!String.IsNullOrWhiteSpace(error)) {
<div class="alert alert-danger">
    <strong>Login failed</strong><br />
    Error received from Google: @error
</div>
        return;
    }

    // Handle the state when the user is redirected back to our page after a successful login with the Google API
    if (!String.IsNullOrWhiteSpace(code)) {

        // Get the state from the query string
        string state = Request.QueryString["state"];

        // Validate state - Step 1
        if (state == null) {
<div class="alert alert-danger">No <strong>state</strong> specified in the query string.</div>
            return;
        }

        // Validate state - Step 2
        string session = Session["Google_" + state] as string;
        if (session == null) {
<div class="alert alert-danger">Session expired?</div>
            return;
        }

        // Remove the state from the session
        Session.Remove("Google_" + state);

        // Exchange the authorization code for an access token
        GoogleAccessTokenResponse response = oauth.GetAccessTokenFromAuthorizationCode(code);
        string accessToken = response.AccessToken;

        // Print out the access token to the user (we really shouldn't do this in a live environment)
<div class="alert alert-info">
    <strong>Access token:</strong> @accessToken
</div>

        // Initialize a new instance of the GoogleService class so we can make calls to the API
        GoogleService service = GoogleService.CreateFromAccessToken(accessToken);

        // Make a call to the API to get information about the authenticated user
        GoogleUserInfo user = service.GetUserInfo();

<div class="alert alert-info">
    <strong>ID:</strong> @user.Id<br />
    <strong>Name:</strong> @user.Name<br />
    <strong>Email:</strong> @user.Email
</div>

        return;

    }

<a href="?do=login" class="btn btn-primary">Login with Google</a>

}
