Voice OTPs: Pioneering a New Era in Authentication Security

We’re living in a digital era where an aura of numerous interconnected devices, applications, and networks continuously surrounds us. While modern technology has streamlined our lives, it has also raised concerns regarding robust cybersecurity.

Admit it, with the advancement of technology and rapid adoption of cloud-based services, the increasing sophistication of cyber attacks is also a major concern for organizations catering to their customers online.

And here’s where organizations realize that conventional authentication, including passwords/PINs and text-based one-time passwords (OTPs), aren’t potent enough to handle high-risk situations.

In response to these challenges, innovative authentication solutions like voice one-time passwords (OTPs) come to the rescue by offering a new paradigm in authentication security.

Let’s understand how voice OTPs revolutionize authentication security and pave the way for seamless and secure user experiences.

What are Voice OTPs?

Voice OTPs are a safe and efficient verification of user identities by delivering OTPs via phone calls. This method allows users to safely authenticate on any platform by offering the OTP received over a call.

Unlike conventional SMS-based OTPs, voice OTPs offer an added layer of security along with a great user experience. Whenever a user tries to authenticate on a platform, the system generates an automated call containing a voice message with the OTP.

The voice OTP is a great authentication method since it reduces the risk of unauthorized access since voice OTPs can’t be accessed or intercepted by hackers in any manner, such as SMS or email-based OTPs.

Furthermore, the voice-OTP authentication method ensures users get a seamless experience throughout their login or signup process, improving customer satisfaction.

How Does Voice OTP Work?

Voice OTP is undeniably a revolutionary, efficient, and secure authentication mechanism. The authentication process works seamlessly by sending a one-time password (OTP) to the user who demands access to the application or network through a call.

The OTP is generated on the user's demand, and a voice call is automatically initiated for the user. Upon answering the call, OTP is read out to the user, and once the user enters this code into the platform, it is authenticated and provided with access.

Business Benefits of Leveraging Voice OTPs

While organizations put their best foot forward in building trust in their customers, offering robust security is often overlooked. Enterprises must understand the importance of a secure and streamlined experience, beginning with a robust authentication mechanism.

Here’s how leveraging Voice OTPs is a game-changer for businesses seeking a reliable and streamlined authentication mechanism in today’s modern digital world.

1. Reinforced Security

Passwords and one-time passwords are always susceptible to unauthorized access and potential security breaches. Cybercriminals are sophisticatedly targeting users and can even bypass multi-layer authentication in some instances due to user negligence or advanced network sneaking tricks.

Here’s where Voice-OTPs take the leap and reinforce the overall authentication mechanism since these OTPs are delivered over voice call, and these calls can’t be traced or sneaked by attackers to gain access to a one-time password.

These Voice OTPs are now used by banking and financial institutions, corporations, and even public sector organizations to ensure every user can quickly access the desired services without worrying about privacy and security.

2. Unmatched User Experience

Adding multiple security layers into the authentication process may enhance user security but eventually hinder the overall user experience.

Your potential users expect great user experiences that are backed by robust security. This means you must create perfect harmony between a great user experience and robust security measures.

Voice-based OTPs offer a seamless user experience since SMS-based or email-based OTPs may take a while, but Voice OTPs are spontaneous, and a user can quickly authenticate.

Furthermore, authenticating from voice OTPs saves time and effort compared to traditional text-based and email OTPs.

3. Helps Individuals with Disabilities

Beyond security enhancements, Voice-OTP eventually embraces inclusivity by helping individuals with disabilities, especially those with visual impairments.

By allowing one-time passwords to be played aloud, this feature ensures accessibility for a wide range of users and reflects a commitment to creating inclusive authentication solutions.

4. Higher Delivery Rates

Businesses face financial losses just because of transaction failure or re-verification. This may also cause them to have higher abandon rates, affecting the overall revenue stream.

On the other hand, Voice OTPs help businesses increase their delivery rates to around 98-99%, much more than conventional SMS-based authentication or email OTP.

Leveraging Voice OTP can significantly reduce re-authentication and re-verification costs and can help lower cart abandonment rates.

5. Affordable

Whether you rely on SMS OTP or Voice OTP, both are equally affordable. However, with voice OTP, enterprises can have a competitive edge since they can reap better outcomes without squandering their capital on expensive email and SMS OTP authentication mechanisms.

Businesses can save a lot of money by choosing Voice OTP authentication and can better utilize the capital in other business activities, including marketing and campaigning.

6. Reliability

Several reasons may lead to SMS or email OTP delays. And these delays do not just affect the user but impacts your overall business reputation.

Whether it’s a lack of coverage or emails getting into spam, the conventional OTP mechanisms may not be as reliable as voice OTPs.

On the other hand, voice OTPs are incredibly fast and reliable and can also be used with other authentication factors for high-risk situations where user privacy could be compromised.

Businesses can combine Voice OTPs with password-based authentication or biometric authentication to reinforce security by adding multiple layers of authentication. This helps create a seamless user experience without compromising security.

To Conclude

Voice one-time passwords (OTPs) offer secure and user-friendly authentication compared to traditional authentication mechanisms.

Businesses can streamline their authentication mechanism by adopting Voice OTPs as they provide numerous business benefits and also help foster customer trust.

With benefits ranging from heightened reliability to affordability, organizations can embrace voice OTPs as a pivotal tool in fortifying authentication security and fostering trust in the digital age.
