Login

Login is a single sign-on tool that authenticates and secures user passwords on behalf of partners who develop video games. It creates a seamless, one-click user registration experience through 30+ third-party authentication providers that offer players convenient, safe, and fast methods for signing up or logging into all of their favorite games. Login uses API methods and allows partners to:

  • Process personal data according to the GDPR regulations
  • Configure the solution from Publisher Account
  • Choose between partner- or Xsolla-side user data storage
  • Authenticate users via username/password or social networks
  • Order social networks according to their use and the user’s location

You can also authenticate users via the Login Widget, which supports:

  • UI customization
  • Localization into 20 languages
  • Automatic delivery of widget updates
  • Widget start page setup

Note: Login Widget is recommended when using Launcher. If you’re already using Xsolla products and want to integrate them with Login, please contact your Account Manager.

Integration Flow

There are two ways to integrate Login:

  • Via API, if you use your own interface to authenticate users in the game, or
  • Using the Login Widget, which features both a user authentication UI and Login API methods.

Integrating Login via API

  1. Create a Login instance in your Publisher Account and specify:
    • Name,
    • Link to the game’s website to connect Login to.
  2. Go to General settings and fill in the following fields:
    • Callback URL to redirect the user to after successful authentication,
    • Allowed origins (CORS) that will be calling the API methods,
    • Error callback URL to redirect the user to in case of an authentication error. If you don’t specify any value, we’ll be using the Callback URL.
  3. Select a user database storage (ours or yours).
  4. Set up the social networks via which users will be able to log in.

Integrating Login via a Widget

    • Callback URL to redirect the user to after successful authentication,
    • Error callback URL to redirect the user to in case of an authentication error. If you don’t specify any value, we’ll be using the Callback URL.
  3. Select a user database storage (ours or yours).
  4. Set up the social networks via which users will be able to log in.
  5. Customize the Login Widget UI.
  6. Connect Login Widget to your website.

UI Customization

  1. Download styles archive from your Publisher Account and unpack it.
  2. Download and install the latest LTS version of Node.js.
  3. Run npm i from the unpacked styles folder.
