Overview

스마트 OTP is a free mobile application developed by Shinhan Bank, designed to enhance digital security for both personal and business customers. The software functions as a mobile authentication tool, generating one-time passwords (OTPs) using NFC (near field communication) technology through the Shinhan Smart KEY card. This service allows users to securely authenticate their login sessions on internet and mobile banking platforms. By simply tapping their smartphone with the physical Smart KEY card, users can generate a time-sensitive OTP, streamlining the two-factor authentication process. The application supports both Android and iOS devices, making it accessible to a wide range of users. It is particularly useful for individuals who require frequent access to secure financial accounts and seek a more convenient alternative to traditional hardware tokens or SMS-based OTPs. The app also enables auto-login functionality and allows users to save login settings for faster future access. Its integration with Samsung Pay further expands its usability, allowing the card to function similarly to a digital wallet. The software is available in both Korean and English, supporting multilingual users within Shinhan Bank’s customer base.
