CA Mobile OTP is a one-time passcode (OTP) app that lets you generate a code that you can use to verify a card or online transaction, or to access an online account. The app supports EMV standards when generating the passcode for authenticating MasterCard and Visa online payment transactions, and also supports HOTP standards for generating one-time passcodes to use when authenticating to Web portals and VPNs.
