miniOrange OTP Login, Verification and SMS Notifications

The WordPress OTP Verification plugin verifies users’ email IDs and mobile numbers through an OTP (One-Time Password) sent via SMS, email or WhatsApp during registration, login, and contact form submissions. This ensures that only genuine users can sign up while preventing fake registrations, spam sign-ups and duplicate accounts.

Add mobile number verification, phone number login, passwordless OTP login, WhatsApp OTP and WooCommerce SMS notifications to your site, with support for WooCommerce (classic and block checkout), Elementor Pro, Contact Form 7, WPForms, Gravity Forms, Ultimate Member, BuddyPress and 30+ other forms.

Note: Enjoy 10 free email and SMS OTPs upon installation to experience the plugin’s functionality.
