OTP is a password validation service that sends a password as an SMS to a defined number and validates this password with its validator service. In MindBehind products, you can use this service before the user starts chatting with a chatbot or live agent. 

 You can use the OTP services in different ways, varying in validator and sender services:

  • The sender service is the one that generates and sends the password to the given number.
  • The validator service gets the password as input from the user and checks the input with the sender’s password.

After these two services agree on the user's input and the generated password is matched, the user can start chatting with the chatbot or live agent.

Three different usage types are available for the OTP service:

Type/ServiceSender ServiceValidator Service
