# 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.
