Signicat’s SMS OTP is a simple identification method based on one-time passwords sent by SMS. A typical scenario may be this:

  1. A user accesses a service on a merchant that requires some sort of identification
  2. A merchant sends an SMS with an OTP to the user
  3. The user types the code in the merchant’s application
  4. The merchant receives the user’s phone number in the response from Signicat

Although this method alone does not provide a high level of security, there are no technical obstacles that prevent merchants from using SMS OTP as a standalone authentication method. However, the most common and recommended use is to use it to boost an existing login process. Integrating SMS OTP with any username/password login solution will result in a 2-factor authentication method.
