1. An image forming apparatus comprising:
a sensor to sense an opening or a closing of a component to access a consumable in the image forming apparatus;
a processor; and
a memory to store instructions executable by the processor,
wherein the processor, by executing the instructions, is to:
confirm an opening/closing history of the component based on a signal sensed by the sensor, as a preset event occurs in the image forming apparatus, and
skip performance of an authentication operation on the consumable in a case where the opening/closing history of the component is not detected for a time period prior to the preset event.
