+title: Alarm Control Panel Entity code validation
+---
+
+The `AlarmControlPanelEntity` is now enforcing validation of code for alarm control panel entities, which set `code_arm_required` to `True` (default behavior). Service calls fail if no code is provided when a code is required.
+
+Previously this was entirely optional, and a user could skip code entry regardless of it was needed by the integration or not (and as such each integration needed to implement its own check).
+
+As the default behavior is that code is required, custom integrations that don't require a code input need to set `code_arm_required` to `False` or the user will always have to input a code regardless of if it's needed by the service calls.
