Autenticación
This instruction shows how to use SDK methods to implement:
- user sign-up
- resend request for a sign-up confirmation email
- user login
- user password reset
You can authenticate users with their username or email address. In the following examples we authenticate users with their username, whereas the email address is used to confirm sign-up and to reset the password.
The logics and interface in the examples are less complicated than they will be in your application. A possible authentication system implementation option is described in the demo project.
Implementar el registro de usuarios
This tutorial describes the implementation of the following logic:
Crear controlador de interfaz
Create a scene for a sign-up page and add the following elements on it:
- username field
- user email address field
- user password field
- sign-up button
The following picture shows the example of a page structure.

Crear controlador de página
- Create a script
RegistrationPage
inherited from the MonoBehaviour base class. - Declare variables for the page interface elements and set values for them in the
Inspector panel. - Add logics to process clicking on the sign-up button:
- In the
Start
method, subscribe to a clicking event. - Add an anonymous method that is called after clicking the button.
- In this method, declare the
username
,email
, andpassword
variables and initialize them by the values from the fields on the page. - Call the
XsollaLogin.Instance.Registration
SDK method and pass theusername
,email
, andpassword
variables and the following methods to it:
- In the
OnSuccess
— called if sign-up is successfulOnError
— called if an error occurs
In the script’s examples, the OnSuccess
and OnError
methods call the standard Debug.Log method. The error code and description are passed in the error
parameter.
You can add other actions like opening a page with a resend request for a sign-up email or opening a login page if sign-up is successful.
Example of a script for a sign-up page:
- C#
using UnityEngine;
using UnityEngine.UI;
using Xsolla.Core;
using Xsolla.Login;
namespace Recipes
{
public class RegistrationPage : MonoBehaviour
{
// Declaration of variables for UI elements on the page
[SerializeField] private InputField UsernameInput;
[SerializeField] private InputField EmailInputField;
[SerializeField] private InputField PasswordInputField;
[SerializeField] private Button RegisterButton;
private void Start()
{
// Handling the button click
RegisterButton.onClick.AddListener(() =>
{
var username = UsernameInput.text;
var email = EmailInputField.text;
var password = PasswordInputField.text;
XsollaLogin.Instance.Registration(username, email, password, onSuccess: OnSuccess, onError: OnError);
});
}
private void OnSuccess()
{
UnityEngine.Debug.Log("Registration successful");
// Some actions
}
private void OnError(Error error)
{
UnityEngine.Debug.Log($"Registration failed. Description: {error.errorMessage}");
// Some actions
}
}
}
Configurar el correo electrónico de confirmación de registro
After successful sign-up, a user receives a sign-up confirmation email to a specified address. You can customize emails sent to users in Publisher Account.
If you are developing an Android application, set up deep links to return a user to an application after they confirm sign-up.

This guide shows how you can use SDK methods to implement user sign-up and login via their social network account.
Unlike for user authentication via username/user email address and password, you don’t have to implement separate logics for user sign-up. If the user’s first login is via a social network, a new account is created automatically.
If you have implemented social login in your application as an alternative authentication method, the social network account automatically links to an existing user account if the following conditions are met:
- A user who signed up with username/email address and password logged into your application via a social network account.
- A social network returns an email address.
- User email address in a social network is the same as the email address used for sign-up in your application.

The examples show how to set up user login via a Twitter account. You can set up all social networks in the same way.
The logics and interface in the examples are less complicated than they will be in your application. A possible authentication system implementation option is described in the demo project.

Inspector panel. - Add logics to process clicking on the login button:
- In the
Start
method, subscribe to a clicking event. - Add an anonymous method that is called after clicking the button.
- To pass a login page URL, declare the
url
variable in an anonymous method. Initialize this variable by theGetSocialNetworkAuthUrl
SDK method by passing aFacebook
value in theSocialProvider
parameter. - To open a browser, call the
BrowserHelper.Instance.Open
method. To use a built-in browser, pass theurl
variable and atrue
value to the method.
- In the
- To get a token and close the browser, track the changes of the page URL after successful user sign-up:
- Declare a

variable and initialize it via theBrowserHelper.Instance.GetLastBrowser

OnUrlChanged
method as a handler.
- Declare a
- To get a token and close the browser, track the changes of the page URL after successful user sign-up:
- Implement getting of the token:
- Use a
ParseUtils.TryGetValueFromUrl
utility method to parse a URL of an active page passed in theOnUrlChanged
method. - Add a check for an authentication code in an active page URL. The
ParseUtils.TryGetValueFromUrl
method passes an authentication code in thecode
variable. - To exchange an authentication code for a token, call the
ExchangeCodeToToken
SDK method and pass acode
variable and the following methods to it:OnSuccess
— called if sign-up is successfulOnError
— called if an error occurs
- Use a
In the script’s examples, the OnSuccess
and OnError
methods call the standard Debug.Log method. You can add other actions.
If a user successfully logs in, the authorization token is passed in the token
parameter. This token is used in requests to Xsolla servers. If an error occurs, its code and description are passed in the error
parameter.
- After you get the token, delete a game object with a browser.
