SDKs for Unreal Engine / Xsolla Login widget

Xsolla Login widget

Xsolla Login widget allows you to integrate a ready-made interface for user authentication into your project and reduce the cost of development for code and UI.


  • The widget only supports the following user authentication methods:
    • classic login via username/email and password
    • passwordless login via a one-time code or link sent via SMS or email
    • web-based authentication via social networks
  • The widget doesn’t work in an external browser. For security reasons, external browsers restrict URLs from third-party applications.

Set up redirecting users to the application after successful authentication using the widget:

  1. Open your project in Publisher Account.
  2. In the side menu, click Login.
  3. Select the Login project and click Configure.
  4. Select the Callback URLs section.
  5. In the Callback URL field, specify the same user redirect paths that you specified earlier when configuring the OAuth 2.0 client.
  6. Click Save changes.

To open the Xsolla Login widget, call the AuthWithXsollaWidget SDK method and pass the following to it:

  • the bRememberMe parameter
  • the OnSuccess callback for handling user authentication and getting a token
  • the OnCancel callback to handle the closing of the widget by a user without authentication (optional)


For standalone builds, the widget opens via the W_LoginBrowser blueprint that comes with the SDK.

You can create your own blueprint to display the Login widget. To do this, create a blueprint of the XsollaLoginBrowserWrapper class and add the necessary functionality to it.

Xsolla provides standard widget templates. Their appearance and content is determined by the Login method chosen for your project and widget customization settings from Publisher Account.
Widget customization is available only after you sign the Xsolla Product Licensing Agreement. To sign the agreement, go to the Agreements & Taxes > Agreements section in your Publisher Account.
