Voice OTP for Enhancing Security with Two-Factor Authentication

Two-Factor Authentication (2FA) offers an additional layer of security for user login sessions and transactions. 36% of people use 2FA to secure their digital accounts. In this post, we’ll explore Voice OTP service and how you can use it to make 2FA more reliable and user-friendly.

What is Voice OTP?

 2FA mainly typically uses a combination of a password and an additional verification method to authenticate users. Voice OTP is a One-Time Password (OTP) that uses voice as an authentication factor. Put, you receive an automated phone call with the code instead of an email, SMS, or push notification.

Why Use Voice-Based Authetication?

1. No Need for Internet Connectivity: Users with poor or no internet access can receive the codes
2. Improved Security: The risk of Man-in-the-Middle (MITM) attacks is low, and voice calls are more difficult to intercept.
3. More Accessible: Voice OTPs are useful for the visually impaired and others may have trouble reading screens

How does Voice-Based OTP Work?

Banking

One of the common use cases for Voice OTP service is in the banking industry. Apart from providing an added level of security during transactions, it helps verify the user’s identity during phone banking.

E-commerce 

Retailers and e-commerce websites can use Voice OTP to confirm order placements, reducing the potential for fraudulent transactions.  

Social Media

Security breaches and frequent account hacking attempts at major social media platforms have forced them to adopt stringent security measures. Voice OTP proves to be a promising solution for social media sites, as it incorporates biometric authentication making accounts more secure.  

Future of Voice Authentication

Voice authentication is still relatively nascent, with limited adoption. However, the ongoing research into voice recognition, natural language processing, and biometrics could lead to the rapid development and adoption of Voice-based OTP. Soon, it can soon be integral to various industries, such as e-commerce, government services, and the health sector.
