Your verification code is
Your customers' accounts are at risk. Here is what attackers are doing to intercept SMS codes.
Attackers convince carriers to transfer numbers to their SIM cards, receiving all OTPs.
Hackers exploit SS7 protocol vulnerabilities to intercept SMS messages globally.
Spyware on devices reads SMS messages before users see them.
Tricking users into sharing codes or forwarding messages to attackers.

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.
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.
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.
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.
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.
