摘要： A system and method is provided for generating a one-time passcode (OTP) from a user device. The method includes providing a passcode application and a cardstring defined by a provider account to the user device. The passcode application is configured to generate a passcode configured as a user OTP for the provider account, using the cardstring. The cardstring is defined by at least one key camouflaged with a personal identification number (PIN). The key may be camouflaged by modifying and encrypting the modified key under the PIN. The key may be configured as a symmetric key, a secret, a seed, and a controlled datum. The cardstring may be an EMV cardstring; and the key may be a UDKA or UDKB. The cardstring may be an OTP cardstring, and the key may be a secret configurable to generate one of a HOTP, a TOTP, and a counter-based OTP.
