Every business and organization that owns an online platform and/or runs business transactions that need security and authentication knows the value of OneTime Password (OTP). This has been in use for many years for authenticating customers’ transactions as well as authorizing online payments to avoid fraud.
How OTPs Work
The way OTP works is by the service provider used by the business or organization requiring OTP to generate a password at random, which varies in length of code. This password is then sent to the user or customer who needs it to authenticate a transaction at the point of request. It is an added layer of security especially for online transactions, being another means of identification aside from the usual username and password.
This has really proven to be very effective in ensuring safe transactions to a large extent, as there might be cases where fraudsters have access to a user’s account or credit card details. However, the OTP authentication can act as the last valuable barrier to being defrauded.
OTPs can be sent through SMS, Email, or Voice. Each of these needs an API integrated with your application to send. Our focus is on how Voice OTP works, given the building popularity and advantages over other OTP delivery options.
How Voice OTP Works
Voice OTP works in a similar way to SMS OTP. You also need to get a Voice OTP API and integrate this into your web or mobile application. Then, when the OTP is requested, it is forwarded to the user’s phone number as a phone call. This is then picked up by the customer, who listens to the recorded audio OTP and input it in the appropriate space.
However, in order for you to get the best from Voice OTP, it is important you choose the best OTP service provider in Nigeria. That is one that offers assured delivery, prompt delivery, and also at an affordable rate. You can check out the SmartSMSSolutions Voice OTP API.
