tpsdk-unity-auth

This package provides an easy way to identify your users in a secure and reliable way from your Unity Project. It's built on top of AppAuth for OAuth 2.0 and OpenID compatibility and Microsoft Identity Model libraries for token validation.

---

Configuration

To configure the package, import it into your project and create a configuration file by clicking on the top menu TiltingPoint > Auth > Configuration.

• For Android, set up your project dependencies by clicking TiltingPoint > Auth > Android dependencies.

---

Usage

Once you've set up the configuration file, you can start using the Auth Package by interacting with the Authenticator class. The following methods allow you to interact with the package:

• Authenticator.Initialize() Initializes the package and pulls the server configuration. Two events will inform you about the result of this action: Authenticator.OnInitDidSucceed and Authenticator.OnInitDidFail.

• Authenticator.TokenExchange() Performs a token exchange request with an external issuer. Two events will inform you about the result of this action Authenticator.OnTokenExchangeDidSucceed and Authenticator.OnTokenExchangeDidFail. The succeed event will return the id, access and refresh tokens.

• Authenticator.TokenRequest() Returns a set of fresh tokens from the user. We strongly recommend to not to cache any of your tokens and use this function to make sure you are always using valid tokens. Two events will inform about the result of this action Authenticator.OnTokenRequestDidSucceed and Authenticator.OnTokenRequestDidFail. The succeed event will return the id, access and refresh tokens.

  • Note: TokenRequest will only work after the user has been authorized via Authorize() or TokenExchange(). If you need an RPT Token for a specify it as the first parameter of the TokenRequest call. For an implementation example, see the SampleScene.unity and `AuthSampleRunner.cs contained inside the Auth Package

Token Utilities

The Auth package provides some utilities to help you work with tokens:

• AuthUtils.ValidateToken() Validates a token. Note: All ID tokens provided by the Auth package are already validated.
• AuthUtils.GetTokenClaim() Tries to get a claim from a JWT token.
• AuthUtils.GetTokenClaims() Gets the claims list from a JWT token.
• AuthUtils.GetTokenHandler() Returns a JwtSecurityToken from a JWT token.
• AuthUtils.GetTokenExpirationDate() Returns the expiration date from a JWT token.

TokenResponse & TokenResponseHandler. TokenResponse is the default structure that contains the raw tokens given by the Auth Package. If access to the internal information is needed TokenResponseHandler will provide some useful accessors. Example:

var handler = new TokenResponseHandler(response);
var idToken = handler.idToken;
Log($"Id Token details:\n" +
$"- Expiration: {idToken.TokenExpirationDate}\n" +
$"- jti: {idToken.Id}\n" +
$"- Email verified: {idToken.EmailVerified}\n" +
$"- TP User Id: {idToken.TpUserId}\n");

External Login Adapters

The Auth package can hook to external login providers like Google or Apple and perform a token exchange after a successful login. Custom Login Adapters can be created by inheriting from BaseLogin

All adapters will inform you about a successful login using two events: Authenticator.OnLoginDidSucceed and Auth.OnLoginDidFail, they will provide you only with the information given by the chosen Login Provider.

After a successful login, a Token Exchange will get performed automatically and trigger Authenticator.OnTokenExchangeDidSucceed or Authenticator.OnTokenExchangeDidFail events.

---

Email Verification

Some external services may require the user email to be verified. You can call to know the state of the user email verification and start the verification process.

• Authenticator.IsCachedUserEmailVerified Checks if the stored user credentials have the email verified.

• Authenticator.IsUserEmailVerified Will force the refresh of your local tokens and check if the user email is verified. To avoid server overloading IsCachedUserEmailVerified is recommended.

• Authenticator.SendVerificationEmail Will send an email to the user for email verification.

These are the events you can subscribe to know whats the state of the verification.

• Authenticator.OnEmailVerificationDidSend Triggered when the email has been successfully sent.

• Authenticator.OnEmailVerificationDidSucceed Triggered when the user email status changes to verified, meaning that it has completed the verification process correctly.

  • Important note: This event will only get triggered when the app is opened, when coming from background after SendVerificationEmail, after forcing a token request via IsUserEmailVerified or TokenRequest(true). With this information in mind, a good practice to avoid users getting stuck in the process if they use another device to confirm the email, is to add a button that calls IsUserEmailVerified that the user can interact with if they have used an external device for the confirmation.

Authenticator.OnEmailVerificationDidFail Triggered when something went wrong sending the verification email.

Important notes

This package was developed for internal use within the Tilting Point SDK and Tilting Point Services and is not recommended for production usage due to the use of Debug libraries and non-secure token storage.
