Recently, in the Einstein gravity, Majhi and Padmanabhan proposed a straightforward and transparent way of obtaining the Bekenstein-Hawking entropy by using an approach based on the Virasoro algebra and central charge. In this work, we generalize their approach to the modified gravity with higher-curvature corrections and show that their approach can successfully lead to the corresponding Wald entropy in the higher-curvature gravity. Our result shows that the approach is physically general.
