  description: >-
    The MessageBird Verify API provides a simple way to implement two-factor
    authentication and phone number verification. It generates and validates
    one-time passwords delivered via SMS or voice call, handling token
    generation, delivery, and verification in a single workflow. The API
    supports configurable token length, expiration time, and delivery
    channel selection for flexible integration into sign-up and login flows.
