OTP by SMS and security code

Principle

The cardholder enters two codes on the authentication page:
  • 1: a temporary code;
    • OSB sends the cardholder an SMS containing a temporary security code (OTP - One Time Password) that is valid for (5) minutes.
  • 2: a permanent code.
    • This security code is transmitted by the cardholder’s bank.
