Library Summaries
Vue OTP Pro
The most feature-complete standalone OTP library for Vue 3. Ships with 11 themes, 5 color variants, smooth animations, full accessibility, IME handling, paste delimiter filtering, and a composable API. ~3 KB gzipped.
PrimeVue InputOtp
Part of the popular PrimeVue UI suite (~470K weekly downloads). Great if you're already using PrimeVue — benefits from the unified theme system and slot-based customization. However, the InputOtp component itself has only 4 core props and no OTP-specific features like auto-focus, complete event, or exposed methods.
Best for: Teams already using PrimeVue who want consistency.
vue3-otp-input
The most popular standalone OTP library (~27K weekly downloads). Good TypeScript support and exposed methods (clear/fill). However, it has known bugs with partial v-model sync, IME/Chinese input bypass, and paste handling. No built-in themes, animations, or ARIA support.
Best for: Simple use cases where you provide your own CSS.
Syncfusion OTP Input
Enterprise-grade component with the best accessibility compliance (WCAG 2.2, Section 508). Offers 8 theme presets and 3 styling modes. However, it requires a commercial license for most businesses, ships as part of a large package (~877 KB), and lacks features like auto-focus, composable API, and paste delimiter handling.
Best for: Enterprise teams needing compliance certifications and have a Syncfusion license.
@healerlab/vue3-simple-otp-input
Lightweight library with an explicit paste toggle and color props for quick styling. Pre-1.0 (v0.0.9) with very low adoption (~350 downloads/week). Has broken TypeScript types field, no v-model support (callbacks only), and no accessibility features.
Best for: Quick prototypes where you need minimal configuration.
What Vue OTP Pro Does Differently
Bugs Fixed
None of the other libraries handle all three of these correctly:
- Partial v-model sync — Setting
v-modelto a value shorter thannumInputsworks correctly - IME composition — Chinese/Japanese/Korean input is validated after composition ends
- Paste delimiter filtering — Pasting
