Why SMS OTP is No Longer Safe

Your customers' accounts are at risk. Here is what attackers are doing to intercept SMS codes.

SIM Swapping

Attackers convince carriers to transfer numbers to their SIM cards, receiving all OTPs.

SS7 Attacks

Hackers exploit SS7 protocol vulnerabilities to intercept SMS messages globally.

Malware

Spyware on devices reads SMS messages before users see them.

Social Engineering

Tricking users into sharing codes or forwarding messages to attackers.

Voice OTP: The Secure Alternative

Voice calls cannot be intercepted via SS7, malware cannot read them, and SIM swaps are ineffective. Your verification code goes directly from our servers to your user's ears.

No Message Storage

Codes delivered via audio leave no digital trail on the device

Real-time Delivery

Instant connection with <3 second average pickup time

Frequently Asked Questions

How is Voice OTP more secure than SMS?

Voice OTPs are delivered via phone calls, not text messages. This means they're immune to SS7 attacks, SIM swapping, malware that reads SMS, and fake cell towers. The code is spoken directly to the user and leaves no digital trail on the device.

What programming languages are supported?

Our REST API works with any language that can make HTTP requests: JavaScript/TypeScript, Python, PHP, Java, Go, Ruby, C#, and more. We provide code examples for the most popular languages.

How do I set up custom voice messages?

You create voices through the dashboard with dynamic parts that can read OTP codes in digit mode. Each voice has a unique name that you use in the API. Voices must be approved before they can be used for broadcasts.

When will WordPress and WooCommerce plugins be available?

We're actively developing plugins for WordPress and WooCommerce. They'll be available in the WordPress plugin repository soon. Join our newsletter to get notified when they launch.

What happens if the call is not answered?

We retry failed calls automatically (up to 3 attempts). You can track delivery status via our API. You can also configure fallback to SMS if voice delivery fails.
