Information security is every service provider's top priority in the current digital era. Users have better control over any action involving their accounts and profiles thanks to the security layer known as OTP.
A user can prevent any type of information leak, fraud, or data breach with this method. OTP has been acting in the capacity of a guardian for a very long time. Typically, a user's registered mobile number receives these OTPs.
Voice OTP serves as an extra degree of security for your users, as stated. As soon as you begin utilizing our service, the risk of data security and phishing assaults is removed. There are numerous applications for it in business. But first, let's learn its definition, how it works, its features, and its advantages.
With the aid of the voice OTP option, businesses can authenticate using the OTP provided through a phone call to the registered phone number. Users can utilize this OTP for authentication in a short amount of time. Every time someone tries to authenticate on any device, the provided OTP is compared to the OTP generated on the server. If the two OTPs match, the businesses have successfully authenticated.
Common applications of voice OTP:
How voice OTP works
The user end or the system end can both initiate a voice OTP request. Similar to when creating an account, a system can either automatically send a voice OTP to the user for verification or the user can voluntarily request this.
After receiving the request, the API creates a random OTP. API uses Text-to-Speech to convert the OTP password into voice. API combines it with the IVR system after it is finished.
An initial call will now be made by the system. The user must answer the call and pay attention to the IVR's delivery of the OTP. The user must now input the OTP in the relevant field before it expires or verification.
Calling a user to deliver the OTP simply takes three easy steps and five to six seconds. These three easy measures will help you provide your user with greater protection and reduce the risk of a phishing attack.
The key features of voice OTP
This service's functionality enables the company to design unique prefixes or conversations before providing the user with their OTP. The system will speak the text that has been entered, followed by the OTP.
The system will always display a dynamic caller ID during voice OTP calls. It will be simple for a user to determine whether the call is legitimate or not.
As a company employing Voice OTP, you may now instantly confirm a user without jeopardizing security. The OTP will sound clearly over the call, and the user can enter it right away. It is faster and safer than other verification techniques.
The system will determine whether a voice OTP is getting forwarded to another number or not whenever one is triggered. If so, the system can take action regarding that number. The system has the option to block the number or warn of an additional verification attempt.
If a user enters a phone number, the system can determine whether it is accurate or not. If a user inputs the incorrect phone number, the system will recognize the issue and prompt them to provide the proper number.
The system will end the call if a user has a voicemail or an answering machine set up. This safeguards the passcode or OTP. To obtain the OTP, human interaction is a must.
Utilizing Voice OTP will result in cost savings of 60–70% for organizations. These OTP calls only cost money when the user answers the phone; calls that go unanswered or are put on hold are absolutely free.
Additionally, when compared to SMS OTP, Voice OTP aids in cost management for enterprises thanks to the ability to set the length of recording for outgoing calls.
Alphanumeric and/or numeric texts, as well as configurable quantities in the API, can be read by Voice OTP. You have the option to have the OTP code automatically repeat as many times as necessary if you can't hear it in time.
You can program it to automatically call back after a defined amount of time if the user has not answered or the phone is busy. Your calls will be recorded by the system, along with the call's status (busy, unanswered, unreachable, etc.).
Compared to SMS OTP, Voice OTP is more secure. To guarantee privacy, one-time password notifications will only be made to the customer's phone number. With this service, the password will only be informed when the customer picks up the phone. This is a fantastic benefit that ensures the security of OTP codes sent through Voice OTP.
