OTP, one-time password, is a method used by merchants to verify the validation of a user’s identity. Usually when a user logs in or trigger an action from a website or an app, the user will receive an OTP verification code on the phone, and the user is required to input this verification code into the website or the app, to successfully login or trigger that action.
To the merchants, the OTP verification code allows them to use a cost-friendly way to effectively and conveniently make verification to their customers’identity. Currently, in the global range, the OTP verification method or SMS verification method is the most popular way applied by big and small merchants in different industries for verification.
Why the OTP verification code is needed?
For example, if a user registers a new account, he or she uses a fake phone number, and this number is recorded by the merchant as a customer. This phone number would have no value since it is a false number, and the merchant couldn’t reach that customer through that phone number. If tons of fake phone numbers are stored by the merchants, the purpose of gathering customers’information and well serving them can not be fulfilled.
As time goes by, the OTP verification code has become a powerful tool worldwide. If you are a merchant, and you haven’t been using this method, we highly recommend it to you.
