# Creating Custom Auth Tasks The authentication system allows you to implement custom tasks such as reading values from your own backend service, or querying stats about the player. ## Implementing Custom Auth Tasks To implement custom auth tasks, override the `BeginCustomAuthTasks` function of your `KronosUserManager` class. If this function is overridden, user authentication will not complete as long as the `OnCustomAuthTasksComplete` function is not called. During this state you can implement your own logic. When you are done with everything, call the `OnCustomAuthTasksComplete` function to signal the system that custom tasks have finished. This will finish authentication. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
