OTP Add-on for Booking Calendar

This plugin is an add-on for the Booking Calendar plugin and requires it to function (version 10.10.2 or newer).

It enhances booking security by introducing One-Time Password (OTP) verification via SMS or email. When a user attempts to confirm a booking, they are prompted to verify the action with an OTP, helping to ensure the authenticity of the request.

SMS verification is provided via the SMS.to service. You must have an active SMS.to account and API key configured in the plugin settings to enable SMS delivery.
