Verino is the only OTP input built on a framework-agnostic state machine with an event system. A zero-dependency core powers six adapters: React, Vue, Svelte, Alpine, Vanilla JS, and Web Components, without reimplementing any logic. It ships with a built-in countdown timer, resend system, masked PIN mode, and support for the Web OTP API for automatic Android SMS retrieval. You also get full programmatic control through setError, setSuccess, setDisabled, reset, and resend.
