CA Auth ID OTP is a One-Time Password compliant to OATH standards. Once the user's account is provisioned, the client application that you build by using CA Auth ID OTP SDK takes the user’s PIN as an input and generates passcodes on the user’s device. The user uses this generated passcode at the Web application that is protected by CA Auth ID OTP authentication. Based on the authentication result, the user is granted access to the protected application.
CA Auth ID OTP also supports the Transaction Signing feature in the Sign mode of passcode generation. This feature conforms to the OATH Challenge-Response Algorithm (OCRA) defined by RFC 6287.
Passcode generation is an offline process, the client application need not connect to the authentication server for generating passcodes.
CA Auth ID 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).
