OTP (One-time-password)

This post is referring to Vahana 2 (beta version). To check the document for production, please go to vDesigner-v1.0

The OTP element verifies the mobile number of users by sending a unique verification code (OTP) during registration or transaction processing. It removes the possibility of a user registering with a fake mobile number. This module checks the existence of the mobile number and the ability of a user to access that mobile number.

Usage

When to use
A business that deals with sensitive customer information can make use of our OTP services. Some examples of the sectors that use OTP services are banking, healthcare, e-commerce, insurance, transport, etc.
