It was at a time when online fraud and criminal activities were getting rampant. A lot of people were taking advantage of lapses in websites security systems and the naivety of some online users to defraud. That necessitated the need for a more secure means of carrying out transactions especially online and gave birth to multiple-factor authentication or most popularly two-factor authentication.
The use of OneTime Password (OTPs) as a form of user authentication or transaction authorization is fast becoming a must-do for many business organizations. And this is because of the many benefits it offers as regards safe and secure online transactions. To send such OTPs, you can do this as SMS or as Email. However, there is also an increase in the use of Voice OTP, either in addition to these other ones or as a sole means to deliver OTPs.
What is Voice OTP?
Voice OTP is basically the OneTime Password that is delivered over voice. That means instead of receiving the OTP for authentication through SMS or Email, it comes as a phone call on the linked phone number of the user who requested the OTP. The person then picks up the call and listens to the recorded audio that reads out the OTP for him/her to use.
Who Can Use Voice OTP?
A lot of businesses use Voice OTP. Most especially if you run a business with an online presence, and where your customers need to authenticate their identity and/or carry out transactions and need to authorize this, you need Voice OTP.
Some businesses or organizations though might use this more than others. Some of the most common users of Voice OTPs are:
- Fintechs: Businesses that have incorporated technology in financial services such as banks, microfinance banks, loan companies, bills payment companies e.t.c fall in this category. See here how Fintechs use Voice OTP.
