In an era where cyber threats and fraud are on the rise, businesses must adopt stronger authentication methods to protect their customers. While SMS-based One-Time Passwords (OTPs) have been the go-to solution for years, Voice OTP is emerging as a more secure and reliable alternative.
But what makes Voice OTP the future of customer verification? Let’s explore its benefits and why businesses should consider making the switch.
What is Voice OTP?
Voice OTP is a two-factor authentication (2FA) method where a user receives a one-time password via an automated phone call instead of an SMS. The system reads out the numeric code, which the user then enters to verify their identity.
How It Works:
- A customer initiates a login or transaction.
- The system triggers an automated call to the user’s registered phone number.
- A robotic voice delivers the OTP code.
- The user enters the code to complete verification.
Why Voice OTP is More Secure Than SMS OTP
1. Lower Risk of SIM Swap & Phishing Attacks
SMS OTPs are vulnerable to SIM swap fraud, where attackers take control of a victim’s phone number. Voice OTP is harder to intercept because it requires access to the actual phone call, not just the SMS inbox.
2. No Dependency on Mobile Networks
In areas with poor SMS delivery (due to carrier issues or spam filters), Voice OTP ensures higher deliverability since phone calls are less likely to be blocked.
3. Protection Against Malware & Spyware
Some malware can read SMS messages, exposing OTPs. Voice OTPs are spoken in real-time, making them harder to capture without physical access to the device.
4. Better Accessibility for All Users
For elderly or visually impaired users, listening to a code is often easier than reading a text message. Voice OTP enhances inclusivity in digital services.
