Happy Coders OTP Login for WooCommerce

by Happy Coders

Description

Happy Coders OTP Login is a simple, secure, and customizable OTP login plugin for WordPress and WooCommerce sites. It enables users to log in using their mobile number via one-time password (OTP) verification, using the MSG91 SMS API, and also supports email-based OTP login.

The plugin supports full-screen and popup login forms, integrates smoothly with WooCommerce, and improves user experience by replacing traditional email/password logins with secure phone-based authentication.

Now, you can fully customize your transactional SMS messages using dynamic variables like ##customer_name##, ##order_id##, and more, directly from the plugin settings.

Watch our quick video tutorial to see how easy it is to set up!
