Use anonymous sign-in#

Anonymous sign-in creates a new player for the game session without any input from the player. It's a quick way for a player to get started with your game.

If a session token is cached on the SDK, then the SignInAnonymouslyAsync() method recovers the existing credentials of the cached player, regardless of whether they signed in anonymously or through a platform account. If there is no player sign-in information, this method creates a new anonymous player.

The following code sample shows how sign in to your game anonymously.

async Task SignUpAnonymouslyAsync()
{
    try
    {
        await AuthenticationService.Instance.SignInAnonymouslyAsync();
        Debug.Log("Sign in anonymously succeeded!");

        // Shows how to get the playerID
        Debug.Log($"PlayerID: {AuthenticationService.Instance.PlayerId}");

    }
    catch (AuthenticationException ex)
    {
        // Compare error code to AuthenticationErrorCodes
        // Notify the player with the proper error message
        Debug.LogException(ex);
    }
    catch (RequestFailedException ex)
    {
        // Compare error code to CommonErrorCodes
        // Notify the player with the proper error message
        Debug.LogException(ex);
     }
}

After implementing anonymous sign-in, it is recommended to integrate with at least one supported external identity provider to allow your players to continue their progress from another device or recover their account, if needed.
