ArcotID OTP is a One-Time Password compliant to OATH standards. The client application that you build by using ArcotID OTP SDK takes the user’s PIN as an input and generates passwords (also known as passcodes) on the user’s device. The user uses this generated passcode at the Web application or at the VPN gateway that is protected by ArcotID OTP authentication. Based on the authentication result, the user is granted access to the protected application.
The passcode generation is an offline process, which means the client application need not connect to the authentication server for generating passcodes.
ArcotID OTP library supports industry-standard passcode generation methods such as, counter-based passwords (HOTP), time-based passwords (TOTP), MasterCard Chip Authentication Program (CAP), and VISA Dynamic Passcode Authentication (DPA).
