Fast2SMS – OTP Login & SMS Notifications

Fast2SMS – OTP Login & SMS Notifications is a free WordPress plugin designed to integrate OTP login, order notifications via SMS and WhatsApp, abandoned cart recovery, cash on delivery (COD) verification, and bulk messaging campaigns into WordPress and WooCommerce sites. The plugin enables site owners to add OTP-based login functionality, enhancing authentication for users. It also supports sending order notifications for various WooCommerce events such as when an order is placed, payment is received, or an order is completed, cancelled, or refunded. For COD orders, the plugin offers alerts and a one-tap OTP verification link, which can help reduce return-to-origin (RTO) rates. Abandoned cart recovery is facilitated with a configurable delay, allowing site owners to re-engage customers who have left items in their cart. Notifications can be sent via SMS, WhatsApp, or both, and users can select approved DLT or WhatsApp templates from their Fast2SMS account, with variable mapping for message customization. To use the plugin, users must provide their own Fast2SMS API key. Messages are billed directly to the user's Fast2SMS wallet at their account rates, and delivery reports are accessible within the user's Fast2SMS panel. There are no monthly fees or per-site licenses associated with the plugin. The solution is intended for WordPress and WooCommerce site administrators seeking to improve user authentication, streamline order communications, manage COD verifications, and conduct bulk messaging campaigns through SMS and WhatsApp.
