Twilio Verify is a scalable API designed to securely authenticate identities using one-time passcodes (OTP) via SMS, voice, and other channels, simplifying the process of identity verification compared to low-level messaging APIs. It handles code generation, message delivery, localization, expiration, and fraud prevention through a single API call, processing over 4.8 billion verifications annually. When paired with Descope's no-code connector, Twilio Verify can be easily integrated into authentication flows without the need for backend logic, allowing for quick implementation of phone-based verification in login, signup, and step-up flows. This integration provides a seamless way to enhance authentication strategies with features like SMS and voice OTP, fraud prevention, and user journey orchestration, making it easier to deliver secure and scalable authentication experiences.
