This study investigates the impact of information security factors on the continuance use of GoPay as an electronic payment instrument in Indonesia, utilizing the Expectation Confirmation Model (ECM) as the theoretical framework. The ECM posits that users' satisfaction and continued use are influenced by their initial expectations and the perceived performance of the service. This research explores how perceived security, data protection, and privacy measures affect user satisfaction and their intention to continue using GoPay. A quantitative method was employed to gather data from GoPay users, with the results analyzed to assess the relationship between security perceptions and the continued use of the platform. The findings are expected to provide valuable insights into how information security influences digital wallet usage in Indonesia.
