Use Cases

Marketing Agency

Marketing Agency

An online user wants to participate in a contest posted on social media. You can’t just post the winner’s name, as this would compromise their personal identity. With voice-based Two-Factor Authentication, you can send a PIN to the winner with 100% accuracy and security.

Financial Industry

Financial Industry

A customer has their phone number registered on a website and has opted-in to use voice-based Two-Factor Authentication. The customer completes their money transfer. The site then generates an authentication call to the user’s phone with a unique PIN.



Your customers complete a buy or sell transaction. Your website then sends a voice call to the user’s previously registered device with a one-time numeric. This enables strong security without being too complicated for the customer.
