Enterprise-level SDK for Unity

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:
    • сlassic 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.
  • The widget is not suitable for WebGL builds with iframes due to redirect restrictions.

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

  • 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)

The widget opens in the built-in browser that is included with the SDK. You can either use Xsolla’s built-in browser or a different built-in browsing solution that allows you to track URL changes. To do this, implement your own methods to open the widget (you can use AuthWithXsollaWidget as an example).

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.
