OTP (One-time-password)

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.

The OTP element has the feature to automatically paste the OTP and then display it to the user after the user receives the OTP on his/her mobile number. If the user enters the OTP in the OTP element, the OTP box also populates earlier used OTPs. The OTP element does not allow the user to enter alphabets and special characters.
